The first step to correcting this error is to unsubscribe from a workshop item or mod, which is very easy to do if you follow the correct steps.

Now you might be wondering, how do I unsubscribe from these workshop items? Follow the steps below:

uninstalling MODS for Unturned
  1. Open Unturned.

Fix #4: Join an Alternative Server

There are tons of Unturned servers out there, and it’s not a good idea to try one that keeps notifying you that the “server is using a modified version of the game.” 

You should probably try other alternate servers to see if the error persists.


There are many unmodified servers, mods, and server organizers. You must be careful in choosing the right servers and mods because some of these servers contain malware. You should also use the fixes listed above in case you encounter an error with such a message.
