Error 5001 – Unable to Add Friends

If you cannot send any new friend requests, try cancelling the pending ones:

1. Open the Blizzard Battle.net application
2. Open the friends list
3. Click the cogwheel icon
4. Choose View Sent Friend Requests
5. Cancel pending friend requests

Once the above is complete, try resending the friend request.

You can also try clearing your cache for the Blizzard desktop app. The steps to do that can be found on our Deleting the Battle.net Cache Folder article.

If you are playing on console, please try clearing the cache and try again. For instructions please refer to the support site for your specific console.

If you still cannot send the friend requests, please submit a new Bug report.

Note: Bugs submitted in-game do not receive a personal response. Instead, they'll be directed to the teams responsible for addressing them.
