How to Fix Hydra Error
Return To The Title Screen
In order to resolve the Hydra Error, return to the title screen to force the game's client to update and reset itself. This is usually enough to resolve the Hydra Error afterwards.
Restart Your Game
Alternatively, a more decisive way to ensure that your game client resets is by completely restarting your game to let the client fully load and update itself, especially when using a platform like Steam.
Turn Crossplay On or Off
Another way to work around the issue is by toggling your Crossplay to the other option, as that tends to refresh your connection to the Killing Floor 3 servers, which may resolve the issue.
What Causes Hydra Error
Client Is In A Bad State
The Hydra Error seems to be caused by the client being in a bad state when attempting to reach the Killing Floor 3 servers.
This usually means that your client may be outdated, or is unable to reach the Killing Floor servers.
Killing Floor 3 Servers Are Down
Another known cause of the Hydra Error is if Killing Floor 3's servers are actually down, either for maintenance or if there are server issues.
If this is the case, the best you can do is to wait out the maintenance and check back later. See our Server Status guide to check if Killing Floor 3 servers are currently online.
