Fallout 76: How to Fix Unknown Server Error

Following the recent influx of new players, all thanks to the success of the Fallout TV series, Fallout 76’s servers seem slow to handle the load. It’s not all bad, though. We have plenty of new Vault Dwellers to adventure with, and there aren’t any queue times to speak of, thankfully. But some of us deal with the occasional unknown server error in Fallout 76. Here’s how to fix that little problem!

How to Fix Unkown Server Errors in Fallout 76

To fix the unknown server error in Fallout 76—a common problem plaguing many—you have a few options:

  • Close out of the game and restart the application.
  • Restart your router/modem to reset your internet connection.
  • Swap your Dynamic IP address for a Static IP address.
  • If you’re using a VPN, shut it off while trying to connect to the game.
  • Open up Steam, right-click on Fallout 76, then select Properties. From here, choose Installed Files and then Verify Integrity of Game Files. Let it run through the process. If you’re missing files or any have become corrupted, they’ll redownload.

You may find the problem resolves itself without your intervention. Sometimes, it just takes a bit of patience. Other times, however, restarting the game is more than enough. But in rare occurrences, nothing works. It’s not your fault; it’s a problem with the game’s authentication servers.

What Causes Unknown Server Errors in Fallout

It’s unclear precisely what causes the unknown server error in Fallout 76. As it’s a common issue that generally occurs when trying to log in, it’s likely a problem with the game’s authentication server.

Alternatively, your connection to the host server may be causing issues due to some interference.
