What you were expecting to happen, and what actually happened:
Closed game and restarted following daily reset. Got this error message. Tried joining via wifi and 5G, but same result. Deleted app and reinstalled, same issue. Been more than an hour now.
How often does this happen? When did it begin happening?
Since today’s reset
Steps to make it happen again
Close app, try to restart app.
It’s not a Gems of War issue. Some small part of the Internet in the area you are located in is confused about how to reach the Gems of Wars server. Probably just some corrupted buffer that will eventually refresh itself.
