While cooperative play isn’t the main selling feature of the Souls series, it’s still one of the most requested mechanics. Considering how tough the bosses in the game can be, being able to summon friends and strangers can be a huge relief. Not to mention that there are Invaders that will try to impede your progress in becoming the Elden Lord. When that happens, encountering the “Unable To Summon Cooperator” error in Elden Ring Shadow of the Erdtree and not finding a fix can be frustrating. A one-solve-all solution can be hard to get since it’s mostly a server-related problem, but these 5 methods should help.
Fixing “Unable To Summon Cooperator” in Shadow of the Erdtree
1. Change the Terms and Agreements’ Language to Fix Unable to Summon Cooperator in Shadow of the Erdtree
More often than not, the Unable To Summon Cooperator error is caused by server connectivity issues. Nevertheless, there is one unorthodox method that you should try to fix the problem. According to Redditors vesper_lynd1 and y0ssarian, somehow opening the Terms and Agreement option and changing the language can work as a fix. The option can be found in Title Screen > Settings > Network menu.
After that, the friend that you want to summon needs to fast travel to another Site of Grace and go back. This will refresh the area and help them reconnect with your game.
For example, you can go to the main menu, and try changing the language from English, to Spanish, and back to English. We assume discrepancies between players’ language settings could somehow act like a region-blocker. Changing it, in turn, will fix Unable to Summon Cooperator error in Shadow of the Erdtree. This hidden, probably unintended setting, makes it hard for different languages to connect.
2. Interact With Another Summon Sign to Fix Unable to Summon Cooperator in Shadow of the Erdtree
Occasionally, a Cooperator’s Summon Sign can be interacted with by multiple people at the same time. Obviously, they can’t appear in more than one place at a time and can only help the first person who summoned them. When that happens, although the Summon Signs still can be interacted with, the actual Cooperator has already been summoned by someone else.
Usually, places near tough bosses are considered “hot zones” of failed summoning by the community. For example, it’s Malenia and Maliketh in the base game; Rellana and Radahn are the popular ones for online play in Shadow of the Erdtree.
