How to fix Unable to Summon Cooperator Error in Elden Ring

If you have problems with an Unable to Summon Cooperator error in Elden Ring, you will first need to check your internet connection. Sometimes, internet issues and issues with your connection can cause various game errors, and that's no different with Elden Ring. 

To check your internet connection, we recommend going to a site such as Fast.com. It is a free tool that players can use to test their internet speed. If you find after using Fast.com that your speed is slower than usual, this could be the cause of the Unable to Summon Cooperator error.

But, if nothing is out of the ordinary, there is not much else you can do to fix the error beyond a few attempts at restarting your router, system, and game. Still, these fixes are not guaranteed to work, and the root of the Summon Cooperator error stems from server issues or a bug in the game. The bug may also happen when players attempt to summon a player who another player has recently summoned. 

Another possible cause of the problem is overcrowded servers or players needing to defeat the Margit Boss. That said, we recommend waiting a bit to summon a Cooperator, as by then, the developers should release a patch that fixes the problem.
