How to fix error code 4 in Marvel Rivals?

Reload game, clear up internet, check game files, or install. The code is usually associated with connection or corruption of files.
 
That error usually pops up when the servers are down or there’s a connection issue.

Try this:
  1. Restart the game and your PC.
  2. Check your internet — maybe switch to a different network or hotspot.
  3. Turn off VPN if you’re using one.
  4. Wait a bit — sometimes it’s just the servers acting up.
If it still doesn’t work, check their official Twitter or Discord. They usually post updates there.
