I can't play ETS2MP due to an unknown authentication error. Help!

Mint Humbug


Hi all. I tried logging on to truckersmp as usual but the server took an awfully long time to log me in before displaying a message saying "unknown authentication error. server couldn't connect to api truckersmp port 443. timed out". While this is not the first time this has happened to me. It seems to be a thorn in the side to solve this time round. Anyone experiencing the same issue?

Hello @Pohchi

Solution 1:

Goto C:\ProgramData\TruckersMP
Delete both core_ets2mp.dll  files
Start Truckersmp launcher as administrator and click on install the files.

Solution 2:

Press the Windows Key + R (Win+R) on your keyboard
Enter "%programdata%" and press Enter (without the quotes)
Find the folder "TruckersMP" and delete that folder.
Navigate to C:\Program Files\ and delete the folder named "TruckersMP Launcher"
Go to our website and re-download and install the Launcher with admin privileges https://truckersmp.com/download/
Open The Launcher with admin privileges and click "Install Available Updates

Solution 3:

Download Ultrasurf.
Run Ultrasurf.
Open TruckersMP in Administrator Mode.
Install the available updates (only the first run with Ultrasurf), wait for it to finish and Launch button appears.
Exit Ultrasurf
