What Does Proxy Authentication Required Mean?
HTTP Status Code 407 Proxy authentication Required signifies that the request cannot be processed because it does not have authentic authentication credentials for proxy servers that are in between the client and server which has the ability to access the resource requested.
Similar to the 401 unauthorized however it states that the client must authenticate themselves in order to access proxy.
The proxy MUST transmit a Proxy-Authenticate header field that contains the challenge that is applicable to the proxy’s target resource. The client can duplicate the request by using the new or updated Proxy-Authorization header fields.
Can Error Codes Hurt My Website?
All error codes can cause negative consequences on your site’s performance in the event that they are not addressed in time.
Let’s consider the error code 404 as an illustration. The more pages with 404 errors you have on your website and the less time visitors are likely to spend on your website. Additionally, the longer you’ve got an unresponsive link on your website as a result, more users will encounter the issue. This can negatively impact the customer experience. This is essential to the performance of your company.
Server-side errors may also cause negative effects on your site. The 503 error, for example is essential for SEO. If you don’t address the issue quickly search engines will consider it as a problem that will last forever and remove the page from indexing.
The first and most crucial step you can make to avoid these types of mistakes is to make sure that your website is properly maintained.

How Do I Fix the Http Status Code 407?
The first thing to do is to create a backup of the website on an additional server that’s not actively operating or even live. Backups should be made on a staging server that’s not “live” or active – which is, if you wish to avoid any further harm to your website. Make a complete backup of your database and application prior to attempting to resolve the problem and alter the system. This will give you a safe test bed to try the various fixes that are possible without damaging any security issues with your current application.
Troubleshooting Client-Side Issues
Double-Check Your URL
One of the most frequent causes of the 407 error is an incorrect URL being typed in the address bar of your browser. For example, let’s say you want to go to the following page: example.com/index.html.
Instead of typing the address, you typed in the following address: example.com/index
This is a minor issue, however, it could result in an error code 407.
That being said the first thing to do is verify the URL to confirm it’s accurate before doing any other step listed below.
Rollback Recent Upgrades
Another cause for the 407 error message is a recent update or install that you’ve performed for your CRM. If you’ve recently made an upgrade, think about going back to an earlier version to get back control of your website.
Uninstall New Extensions, Modules, or Plugins
Extensions or modules and plugins are well-known to enhance capabilities and features that go beyond what is typically available in the box.
Did you know that these add-ons could completely control the system?
It’s true!
They could take over your system, and alter your PHP program, CSS, HTML, or even your database.
If you’ve recently installed a new feature be sure to remove these.
If you require assistance in removing a specific extension, just Google the extension’s name in order to locate the official documentation. This should allow you to remove it in the most secure way you can.
Check for Unexpected Database Changes
This is a shocking additional fact:
The removal of an extension may not completely reverse the changes created from the extension.
Actually, certain extensions, specifically for particular extensions, especially on WordPress platform allow access to the entire database, and even modify the records in tables that belong to other extensions, too!
The most effective thing to do is to open up every table individually or manually go through them all for any data changes that are a result of the plugin you are using. Also, you could conduct an online search and find others who have had similar issues to find out what they did to resolve the issue.
Troubleshooting on the Server-Side
Have you tried all of the steps to troubleshoot that were outlined above but you could not get it to work?
In this situation then, you should try some strategies for troubleshooting for the server-side.
Let’s get started!
Check the Configuration Files
The next step to troubleshoot is to determine for any intentional redirect instructions within your configuration files for your web server.
The application you are running is either Apache or Nginx web servers. If it is determined to be an Apache server the apache_server as well as .htaccess should be examined.
However in the case of Nginx only one file is required to be checked: the nginx_conf_. Once you have located the files, look for errors with 407 and check what appears. If so it, you should alter the file to fix it. It is either best to eliminate it completely if you do not require the status code, or to apply it to the particular page.
Check the Application Logs
The application logs function as your site’s diary, which details what pages were visited and which servers it linked to.
If you check the application’s logs to check for an error code 407 typically, there’s some sort of pattern which will direct you to the correct direction for solving this issue.

The HTTP Status Code 407 Proxy Authentication Requirement is the same as 401 Unauthorized.
