How to Fix 501 Not Implemented?
To find out what’s causing an HTTP 501 Not Implemented Error, follow these troubleshooting steps:
Check for Software Updates
501 errors can be generated by old software that needs to be updated. Keeping your software up to date is a good idea even if you aren’t experiencing HTTP 501 Not Implemented Error.
Clean Browser Cache
To prevent the HTTP 501 Not Implemented Error, the method is to empty the cache of your browser. Each browser has its own settings.
- Navigate to Settings > Privacy and Security> Clear browsing data in Google Chrome.

Reload the Page
You can refresh the page. When a website gives you an error of any kind, this is usually the first thing you should do. That way, if there is a mistake or a glitch, you can submit your request again. To reload it if the refresh doesn’t work, try doing CTRL (or CMD) + SHIFT + R.
Configure your proxy settings
A 501 error or other browsing issues can arise due to proxy settings configured on your device or within your web browser. Proxies can reroute your internet traffic, which can cause issues for certain websites’ regular operations even though it can be helpful for anonymity or getting around content restrictions.
- Access the Windows Settings. Go to Internet & Network.
- Select Proxy from the sidebar.
- Disable the Automatically detect settings under the Automatic proxy setup section.
- In the Manual proxy setup section, turn off the option Use a proxy server.
- Close the Settings app.
Scan your Computer for Virus
This error appears when a virus or malware is present. It’s a good idea to scan your computer and make sure your antivirus software is up to date.
Contact the Server Host
If all else fails, contact the server host. 501 errors are almost always related to a problem with your host server, even though you can occasionally fix them yourself. So, if you haven’t fixed the problem, you should contact them as soon as possible.
