Troubleshooting Proxy Errors: Resolving Common Network Issues

Proxy errors are not that uncommon, but they are a problem because they put you and your identification at risk. You may have a proxy error with network notification, or you may not know why your proxy is not working at all. If you have a proxy error, there are several possible concerns that could be causing the problem. To help you avoid them, we have broken down some of the most common proxy errors and offered solutions for them here.

Proxy errors should not happen. If they do, you likely need to make a few simple changes to improve your connection. Let us help you to do that here.

What Is a Proxy Error, and Why Do They Happen?

A proxy is an intermediary that works between your device and the website you are trying to reach with your request. A proxy hides your IP address and presents its own IP address to the website, protecting your identity. Various types of proxy code errors can occur, often meaning some component of the setup or execution process is not working as it should.

A proxy error means that there is something wrong with the proxy itself – however, this is nearly always a problem related to the setup of your proxy rather than with the proxy server. That’s why you’ll want to dive in deeper to determine what a proxy error with network could mean to you.

Error: You seem to be using a VPN or proxy release

If you receive this message while you are using your proxy, that typically means that your VPN or proxy has been noted. In other words, the website you are requesting content from realizes that you are using a proxy.

This ultimately means they have detected and blocked your connection to the site because a proxy or VPN is being used. Websites tend to do this often because they want to control who is accessing their content or have oversight into why they are doing so.

Here’s an example. One of the most common times this occurs is when Netflix blocks proxies. Netflix often hosts live events. When they do, they do not want everyone to have access to them, and ultimately, they may even control which areas have access. They up the game to determine if people are using a proxy, and if they do, they block your access.

Fix it: To fix this problem, you may need to switch to a more suitable proxy. For example, if you are using a data center proxy or a free proxy server, it is easier for these devices to detect and block. Instead, use a residential proxy.

Ultimately, if you receive an error message about a VPN or proxy detection, you will need to change your proxy or not use one to access that content.

Error: 502 proxy error

What is a 502 proxy error meaning?

Typically, this is a server error. However, there are various situations in which this type of error may display when you are navigating the web. If you encounter this, it typically means there is a concern with the proxy and upstream servers and addresses.

Fix: The simplest solution to this type of problem is to reset your connection. Refreshing it is generally all that is necessary in most situations.

If that does not work, a second step is to check the status of the site you are trying to reach. In some situations, you will see the 502 proxy error displayed when the site you want to get to is actually down for unrelated reasons.

In rare situations, this could be a problem with the proxy itself. For example, if you can access the site with another device that is not using the proxy but receives a 502 error when using the proxy, that could mean it’s been detected. If refreshing does not work, you may need to choose a more appropriate proxy, such as a residential proxy.

Since most 502 bad gateway errors are not directly related to a proxy error with network, we will leave it at that. However, you can learn more about these errors at HubSpot.

Error: Proxy Error with Network 3DS (Gaming Hardware Proxy Issues)

If you are still using your 3DS – and why wouldn’t you if you have one – there is a chance that you may find yourself with an error in the system’s functionality at some point. You can and should use your 3DS with a proxy. Doing so can provide you with a better level of security or protect your child who is using the 3DS from revealing their true location or identity.

Gaming hardware proxy issues are not uncommon, and they can happen for a variety of reasons. There are various situations in which a 3DS may not connect with your proxy. Most of the time, you will need to reset the proxy and then try again.

Fix: If resetting the device and connection does not work, the next step is to change your proxy server settings on your Nintendo 3DS. You can do this under the HOME menu, where you will select the “Settings” icon. From there, go to “Internet Settings” and then “Connection Settings.”

This is where you should see a way to “Change Settings” and you can then click the error to go to “Proxy Settings.” If you have the wrong information here, that could be a part of the problem. If you are using a proxy, you need to first click the “NO” option and then click “Detailed Setup.” On this page, you need to enter the information and then tap both “OK” and “Save” – often, it does not save this change, and that leads to the proxy error.

Error: Authentication Errors

Authentication errors can occur in several situations. One of the most common is a 407 Proxy Authentication Required error message, which indicates that the proxy server needs to be authenticated.

Other times, you will receive an “Invalid credentials” proxy error. This also means that the system is unable to authenticate the information you provided.

Fix: To fix this problem, you’ll need to go into the device you are using, go to the internet connection settings, and update the proxy information there. For some reason, the system is not able to log into your proxy, and this is nearly always because of a mistake when typing in the username or the password.

If this happens suddenly and you have been using the proxy prior to that, the proxy password may have expired. Some proxy settings will expire over time, requiring you to update them. Most of the time, this type of error is an easy and fast fix for you.

Error: 3XX Redirection Proxy Error Codes

You may receive this error message when the resource you want to use is no longer there. Redirection errors are messages sent to you from the severe when that resource cannot reach the specific asset you are trying to reach. It may no longer be available, or in some situations, it may have changed.

This is a type of informational error, meaning there is nothing really wrong with your proxy setting, but rather, the end server has a problem displaying the information you need.

Fix: If you receive a 3XX redirect error, you usually just need to wait a few minutes. They will generally automatically redirect your access to the right location, so you are not likely to have to do much to fix it.

Here is a list of some of the most common 3XX redirection proxy error codes you may experience:

• 301 – Moved Permanently: This error means the resource has been moved permanently.
• 302 – Found: This error means that the resource has temporarily been moved to a different location and has a new URL. Your browser should automatically redirect you to the new resource. However, the old URL may still work at some point in the future.
• 304 – Not Modified: This error can be more straightforward. It means that the resource has not changed since your last visit. As a result, your browser will generally use the cached version for faster loading, but this does not mean the resource is not available.
• 307 – Temporary Redirect: This error is only slightly different from a 302 error. This specifically means that the request method and body remain unchanged when the redirect request is made. In this situation, you have the ability to submit data to an old URL. That data will be sent to the new URL.

There are numerous other proxy code errors and a wide range of ways to solve them. You can learn more about those in our guide on Proxy Code Errors: What They Mean and How to Fix Them.

More Common Proxy Errors and How to Solve Them

While many of the proxy error with network or other problems are related to codes, there are a few more queries to consider. The following could help you navigate through some of the more challenging concerns that show up.

Error Message: Proxy Error: Could Not Proxy Request

You may receive the following message. “Could not proxy request” as a proxy error, followed by “Localhost:3000”. This error is typically indicative that the localhost package you are using some component of code that is inaccurate.

Fix: To fix this, you need to first check to ensure the port availability is accurate. You can do that using netstat. If that is accurate, and your localhost is defined accurately, there could be a flaw in some other component of your code. Sometimes, you also need to restart the server to meet this challenge.

Error Message: Proxy Error While Downloading

In some situations, you may get an error message like this one “error while downloading.” It may include a second line reading, “Timeout while trying to determine directory size.”  This type of error message often occurs when downloading folders that contain files and sub-files.

Fix: This could mean various things, but the most common problem is that there is a timeout that does not provide enough time for the download of a large number of files. If that is what you are facing, visit your configurations and adjust the timeout seconds to a longer period of time to give it more opportunity to download.

Proxy Error FAQs: If You Still Have Concerns, Check Out These Answers

What Proxy Error Means

When you see “proxy error” that means there is some concern related to the proxy server. Typically, it means the proxy server cannot process your request to access a website or some other online resource. There are various reasons this can happen, including the long list of HTTP error codes and any of the above-listed problems. If you see a proxy error message, it means you need to make some changes in order to use the proxy for the tasks you are completing. Common problems include:

• Incorrect proxy settings
• Issues with the end proxy server
• Network connectivity problems
• The target website itself may be the culprit

What Does Proxy Authentication Error Mean?

In some situations, you may receive a proxy authentication error message. This may be read, for example, “407 Proxy Authentication Required.” This type of error message means there was some reason that the request you sent could not be fulfilled by the server, which was a lack of valid authentication credentials. If a proxy server is being used, there are still requirements for authentication – such as having the proper credentials for using the proxy in the first place. You will need to verify the credentials to ensure you can get authenticated to continue.

Why Am I Getting a Proxy Error?

There are many times when you have gone through every one of the errors you could find, and you are still having concerns. Unfortunately, there is no way around this until you determine the underlying cause. So, why are you getting a proxy error?

Suppose you are unsure what is causing the problem, and you have rebooted everything and ensured your login information is accurate. In that case, you may need to contact the proxy provider to determine if there is a concern. Sometimes, this will clear on its own, but if it lingers, contacting the provider could be necessary.

How Do I Disable a Proxy Error?

If you want to disable a proxy error, you can do so by changing the settings in your browser to remove the proxy use. This is done under the System icon on your computer, navigating to the computer’s proxy settings. Switch it off, and you will be able to stop using the proxy.

Why Am I Getting a Proxy Server Error?

Most of the time, you will receive a proxy server error for one of the following reasons:

• Your settings are inaccurate. This could be due to a firewall configuration, a DNS setting, or sometimes, it is directly related to your proxy settings.
• Your browser is outdated. If you have not updated it in some time, do so now. If you do not, it may have compatibility issues with the proxy server or with the website that you are trying to access.
• You are using browser extensions that are not compatible. If you have browser extensions in place, these can sometimes get in the way of the proxy settings. Check to determine if you have changed any extensions or if any are outdated that could be causing the concern.
• You have a connection issue. It is not uncommon for a connection issue to cause a lack of functionality. For example, the website may be experiencing a connection timeout or a server outage. That could lead to a proxy server error that may be hard to fix (unless the connection error is on your side).

How Can I Tell If a Proxy Is Blocking Something?

Testing proxies is an important part of using them in some use cases. It can be hard to tell if a proxy is blocking something because the proxy’s job is to do just that – limit who can see what is occurring. One step you can take is to try accessing the website you want to access and find out if there is a lag or any type of connection issue.

Additionally, there are tools that you can use, such as an IP database. Your goal with these tools is to check the details of your IP address.

How Can I Tell If Traffic Is Going Through a Proxy?

Let’s consider the other side of the question. What if you are a website owner and you want to know if people are using your website through a proxy service? In some situations, you may be able to tell because you are receiving a large number of requests from the same IP address. If you look carefully at those requests, you may notice that, while they have the same IP address, they are using different operating systems or browsers. If you notice that, this is a clear indication that you probably have an IP address from a proxy. It is possible to then redirect or block these if you determine they are a proxy and you do not want them accessing your site.

How Can I Quickly Fix a Proxy Connection Problem?

You’ve run into a new proxy connection problem, and everything was fine before it. What do you do? In this situation, a quick, common fix is simply to refresh the page. Then, check and reconfigure the proxy settings, even if you know they are right. A final step could be to clear your browser cache and try the process again.

How Do I Know a Website Is Blocking My IP Address?

If you are struggling to connect to a specific website and you are using a proxy, you may quickly believe that the proxy is the concern. It could be. To find out, try connecting to the same website using a different IP address. For example, try to connect through a different connection. Instead of your WiFi, for example, use your mobile data to connect. If you get through, then the site is likely blocking your IP address. If you are still blocked, it could be that there are connection issues with the destination website.

Why Do Proxies Stop Working?

In some situations, a proxy may stop working because you are using the wrong type! There are various types of proxies available, and some work better for specific tasks than others do. You also have to consider if the proxy has been blacklisted.

For example, residential proxies are ideal for large-scale processes. These are more authentic-looking, meaning they provide you with the highest quality of resources. You can definitely use them for web scraping. However, in some situations, it may be best to try rotating residential proxies. This will give you more access to sites with less risk of detection.

If you are selecting a proxy for your business and want to ensure a reliable proxy is on board, one of the best ways to do that is with a data center proxy. This will give you more privacy, but some data center proxies are easily detectable as bots, which could limit your connectivity.
