iOS Unity game - error log review

We've got a game that is on Android and iOS. A lot of iOS players have messaged and said that they can't get connect to the game anymore. It works perfectly fine on my device but there are a significant number of people are experiencing this issue and it seems like players who are in the database for a while with iOS are not able to reconnect to the game. We have some error logs sent in by some players and we need someone to help us understand what it means so that we can get it corrected. I can send two sets of error logs along with screen recordings to show the problem. This is an urgent situation - so any help/support would be truly appreciated.
