Getting “Unknown Error Code 220” in Marvel Rivals — any idea what’s causing this?

[AnnisHayma]

I keep getting an “Unknown Error Code 220” when trying to log in or start a match in Marvel Rivals. Has anyone figured out what this means or how to fix it?

The issue denoted by the "Unknown Error Code 220" in Marvel Rivals is a communication problem between the server and the client, which usually occurs at the time of login or when the player is trying to join the matches. To resolve this issue the first step should be to check the status of your internet connection and the server, and then you can try to restart both your router and PC, and if that doesn't help you can look through the game files or modify your firewall settings.

It usually shows up when the servers are unstable or your network is dropping packets. Try restarting the game or switching networks, it’s mostly a server-side issue.
