The reasons that can lead to 401 Unauthorized error majorly include problems with the server. The complete list of reasons is as follow:-

• It can happen when the server rejects the user request for some reason, despite the fact that the client has provided valid authentication credentials.
• The server has banned the user’s system for some reason.

Ways to Fix 401 Unauthorized Error

The methods to resolve 401 Unauthorized error involve Flushing DNS records, Clearing Browser and Firewall cache, and checking with the host provider. Let’s look at these solutions in detail:- 

Solution 1- Cleaning Browser and Firewall cache

Browsers create cookie and cache files every time users visit a website so that they load faster when they visit the same website. This is referred to as caching. Invalid login information stored locally in users’ browsers can hinder the logging-in process, resulting in a 401 Unauthorized Error. Most modern browsers allow you to clear your cache in a matter of seconds. Try to access the website after clearing the cache files. If the 401 error code still appears on your screen, the reason could be a cache of your firewall.

Authentication errors could be caused by your firewall not functioning properly with the server. The method for fixing it depends on the type of firewall users have on their system. The procedure is similar to that of most firewalls, and it includes clearing the cache of your firewall.

Solution 2- Flushing DNS Records

DNS errors don’t usually pop up but can sometimes result in a 401 Error. All users need to do to fix this is flush your DNS records. Delete temporary data from your computer by flushing your DNS records. When you try to access that problematic URL again, it will make a completely new request and reauthenticate. The process to flush your DNS depends on the system you are using:-

• For windows, open the command prompt and type in ipconfig/flushdns, and press enter
• For mac users, open the command prompt and type in killall-HUO mDNSResponderin Terminal

Solution 3- Checking with the Hosting Provider

In a situation where none of the above mentioned solutions work, reach out to your host provider and check with him if there are any limitations on his end. Ask him to reset your internet settings and then check if the error still persists or not.
