Almost every game I play has the same connection issue. Some random number of minutes in, I disconnect from all other players. There is no ICE notification afterwords that it is reconnecting. When I go back to the client, the lobbies are all invalid until I refaf.
This is the error that occurred in the clent log at the time of the DC. Note that I left the game 2 minutes later:

This is one of many similar errors that occured for each player at the time of the DC in the ICE log (I also briefly DCed from another player about a minute earlier, and that caused the same error):
