I see this error in XCode, after initializing game center. It says that the communication with the server is a problem, but leaderboards are working fine. I am using the Social functions, Game Center is initialized correctly, and leaderboards are working fine. However, after initialization, I get this error when Social.LoadAchievements function is called, accompanied by “Error: no achievements found”. When I try to submit an achievement, I get the “Failed to report achievement” response. Achievement is registered on itunesconnect, and so is a leaderboard, but this is happening. Anyone with the same problem?
Failed to load achievements The requested operation could not be completed due to an error communicating with the server. No achievements returned
I ran into this same problem this morning. Following this post.
