Keep Trying to Summon

Especially in busy areas, other players might snatch up summon signs before you can. Keep trying to summon until you’re successful.

The “Shadow of the Erdtree” area can be problematic for summoning because of the higher difficulty of bosses. If it’s an area where you find a particularly tough boss, you just have to be persistent and keep trying. The trick is to be fast, stand near the summoning pool and grab the opportunity among all the players looking for help.

Some Other Things to Try:

• Make sure there is no password set because this will block you from interacting with random players.
• If you’re on PC, you can try flushing your DNS or resetting your network adapter.

If none of these solutions work, it’s possible the Elden Ring servers are experiencing issues. You can check online to see if other players are reporting similar problems and wait until the servers are more stable.
