So our server suddenly stopped connecting to matchmaker. I tried to reinstall rFactor2 with fresh .plr file etc. but still had the same problem. Where it usually says Matcher Status: Server added succesfully, or something like that it's empty right now. Wondering if something was changed on ISI side to make it not to work on our server for some reason?
It has happened to me because of an error when i packaged the mod. Try to build the mod another time.
It's not a mod problem, nor server firewall problem. We think it's a hardware firewall that we cannot make any changes.
