What I tried to do to fix this issue:
*Validated my ETSM2. (files are good)
*choosing different servers including: US1, SA1, Asia1, and one of the EU servers. (they were NOT full at the time)
*Set ETS2 MP, EST2, and Steam to run as administrator.
*Reinstalled ETS2MP several times. (with and without LateAutumnMod)
*Checked windows firewall and see ETS2 was already enabled for private access and even have enabled so it also has public access. Have also added ETS2MP and allowed access.
*Fully disabled windows firewall and antivirus (Bitdefender free edition).
*Disabled my routers firewall.
*Opened UDP/TCP ports: 42850, 15698, 30033 (ETS2MP ports? found on another thread)
All I see is a red "OFFLINE" text on the top right and on the bottom left corner of my screen is repeating messages of connection issues. (quote above/attached screenshot)
