Gotta Go Fast!

Summoning other players to help you out with a boss fight is one of the most useful features in FromSoftware titles. Sometimes you need some jolly cooperation, to get through a difficult section together. However, when that doesn’t work it be quite frustrating, especially when you’re having a hard time. If you keep running into the ‘Unable to Summon Cooperator’ error in the Elden Ring Shadow of the Erdtree DLC, here are a few things you can do to fix that.

Fixing the ‘Unable to Summon Cooperator’ Error Elden Ring Shadow of the Erdtree DLC

Similar to the early days of Elden Ring when there were simply too many players in-game, the release of Shadow of the Erdtree has boosted the concurrent player count significantly.

This means that any summon sign you see is probably being activated by multiple players, and it’s a matter of just doing it fast enough. Failure to do that leads to the ‘Unable to Summon Cooperator’ error. There isn’t really anything you can do externally, but here are a few suggestions.

  • Stand right next to the summoning pool, and stay still until the sign appears. As soon as you see it, activate the summon sign. It’s a timing thing really, and you’ll need all the speed you can get.
  • Make sure you aren’t using a password which would limit the summoning.
  • Restart the game, or load into your profile again.
  • Make sure your internet connection is stable, and restart the modem just in case.

Apart from that, you could try playing at a time when the game isn’t as active, but we doubt that will be the case for at least a few days. The expansion just came out, and people are playing it non-stop. Additionally, given the high difficulty of the expansion, more players are likely resorting to summoning, making it even harder to get help.
