Warhammer 40k: Space Marine 2 multiplayer Error Code - 1: Possible fixes, reasons, and more

Many of the Emperor's faithful have been running into the Warhammer 40k: Space Marine 2 multiplayer Error Code - 1. It's unclear why this keeps happening. However, during an Operation or Campaign, players will be booted from the host's lobby and sent back to their own. At times, this also results in the game crashing and needing a restart.

There's nothing that dampens the spirit more than not being booted from a good session of purging Xenos.

Here are a few solutions you could try to solve the Warhammer 40k: Space Marine 2 multiplayer Error Code - 1.
