Having friends trying to join me and get a “connection timeout” error and when I try to join one of my friends I also get the same error.
The way that we resolved this was that I would host a public quickplay and then for him to do a lobby browser search for my name.
- was not able to join friend using steam invite(vice versa)
- Got “Connection Timeout”
- Was able to fix using QP
Let me know if there is anything else I can provide to help.
