If you're seeing "Error Code 0: Connection Timed," then this usually means your game is unable to contact SnowRunner's servers. Can you check that your PC or console is connected to the internet, and is not being blocked by a firewall?
Can you also check to see if you find other online features, such as multiplayer, are also not working? Unfortunately, if this is the case, you will need to report this to the developers, you can open a support ticket with Saber Interactive here: https://support.saber.games/hc/en-us/categories/6056441571345-SnowRunner
