If your server is not starting, please attempt following the chain of action before contacting us:
Step 1: Ensure that you have waited 5-15 minutes for the server to start (ARK servers can take a fair amount of time to start up depending on what they are doing).
Step 2: Verify the server's state by checking if the server is visible from your Steam favourites list. Learn how to do that here.
Step 3: If your server is running mods, try disabling them via the Commandline Manager and/or deleting the 'Mods' folder in ShooterGame/Content. We always recommend following the next step after removing mods, as they leave traces behind which can prevent the server from starting up as well.
Step 4: Try renaming your SavedArks folder (ShooterGame/Saved/SavedArks), this will result in the server generating a new folder. You can rename it back to SavedArks later on and nothing will be lost.
Step 5: Run a Steam update on your server from the control panel. Simply click the 'Steam Update' button and continue. An update window will open and you will see a log of what is going on. Note that the console/log window that will open does not update in real-time.
