Error Code 2100 in Marvel Rivals is a very annoying login or connection issue that prevents players from joining a match. Being one of the best esports games out there, this hero shooter requires a stable connection, and this error code has become increasingly common in recent updates, especially for PC players with wired connections.
This problem usually occurs because of temporary ISP routing issues, conflicting Wi-Fi or Ethernet signals, or server handshake issues during peak times. According to reports, it has been affecting players across the world. Moreover, players with high-latency internet connections are making this problem worse.
