I tried uninstalling and deleting the game, restarting the phone, changing time once again (since the problem began after I changed the time since I noticed that the time is ahead by few minutes), vpn but nothing is working.
The authentication issue is a separate problem, and the two issues should not be mixed together.
Error 500 is a generic “unknown” error. It can be caused by many different factors, so it is not tied to a single root cause.
The authentication issue, on the other hand, mainly affects iPad devices (although not exclusively). It appears to be related to changes Apple made to some of their services and frameworks, similar to the changes they introduced to their purchasing system (Important Notice: Unauthorized Third-Party Top-Ups Are Prohibited). Our team has already updated our implementation, and this issue should be resolved with the release of version 3.6.1.
The Error 500 is a different issue altogether. It occurs only occasionally and, in many cases, resolves itself without any intervention. In other cases, further investigation may be required to determine the underlying cause.
I found a solution to my problem. I changed the time back to the one before the error (how much further the time was ahead) and successfully logged in. Later I changed the time to the current one (with the game on) and everything is working
