2] Remove Minecraft mentions from the Hosts file
The Hosts file in Windows is basically used to map hostnames to IP addresses. In case the Hosts file consists of conflicting information regarding Minecraft or the game publisher, i.e., Mojang, you might end up receiving the ‘Not authenticated with Minecraft.net’ error. If you are receiving this error because the hosts file is pointing to an incorrect domain, you can resolve the issue by making a simple tweak to the Hosts file.
Here are the steps to remove Minecraft mentions from the Hosts file:
- Firstly, open the Run dialog box by pressing the Windows + R hotkey.
- In the Run dialog, type and enter “%SystemRoot%\System32\drivers\etc” which will open up the File Explorer with the Hosts file.
- Now, right-click on the Hosts file (not the hosts.ics file) and select the Open with option. Then, select the Notepad application to open the file.
- Next, scroll down to the bottom of the file and check if there are lines with mentions of Minecraft or Mojang. If you find any such mentions, select the lines and delete them
- After that, save the hosts file to apply changes.
- Finally, reboot your PC and see if the error is resolved on Minecraft.

3] Disable or Uninstall GPN like WTFast
In case you are using a GPN i.e., Gamers Private Network like WTFast to improve game latency, it can cause this error. Some affected users reported that their GPN or equivalent software caused interference with certain Minecraft servers like Hypixel, which resulted in this error. If the same scenario applies to you, disable your GPN and then check if the issue still persists.
If the error persists, there may be another reason behind it. So, you can try the next potential fix to resolve the issue.

You are likely to receive this error if you are using an account from a doubtful or questionable third-party website like Mcleaks, Mineshafter, etc. Therefore, ensure that you are using a legitimate account to avoid this error and successfully join a server.
5] Contact their Support team
If none of the above solutions work for you, please contact Mojang’s official support team. Just submit an Account Support ticket with an explanation of the error. They will respond within 24 hours to assist you with what to do to fix the error.

What does it mean when it says failed to authenticate your connection?
The error “Failed to Authenticate Your Connection” in Minecraft prevents you from joining a server. A bug in the server itself may cause this error. Alternatively, it may be a result of being connected to an unstable internet network or experiencing other internet-related issues.
