Having Trouble installing multiplayer

Please describe the issue you are having in as much detail as possible: Im giving my cousin a step by step to install The multiplayer launcher and the launcher keeps saying it cant connect to the servers or a fatal error. Can someone help us?

Please provide any evidence or demonstrable content of the issue:

Could you send screenshots of the errors?

Here is the picture he sent me. We just finished building his start PC too

Could you try Manually updating the Launcher - BeamMP Docs?

Do i follow this link?

Yes, and then follow the instructions on the BeamMP docs page.

It worked. Thank you
