[2024] Server Authenticaton Error

Servers now require a login via SLG account. Your game server provider needs to update their systems to allow you to enter these credentials.

The reason is the same as for why Valve requires you to get a token from a Steam account with verified mobile phone number to host a Counter-Strike or similar server - enforcing Terms of Service. Hence an opt-out is not possible.

Yes, it works without account in offline mode.

Of course both the server and the client need to be in offline mode, the mode is intended for when you are actually offline.

You need to either use -username= and -password= OR -userToken= with a token from play.eco in the command line parameters to start a server. If your host hasn't provided means to add those yet, you should reach out to their support to make that available. Configuring the login via config files is not possible.

These containers were once used internally and are provided as-is without support or warranty. So the "official" in it is limited to that we still build them, but they are not maintained. As far as I know there is no environment variables for these inputs.

Originally posted by Sm91cm5leU9mQmVpbmc=: of course it not official and not maintained, but why image called "strangeloopgames/eco-game-server" btw

command: ["./EcoServer", "--nogui", "--username=*username*", "--password=*password*"] * - just a mark

Because we created the docker container for our internal use and just published it for experienced users to potentially make use of it as-is, as it's there anyway. The respective additions you noted have been communicated on Steam forums, in Discord and can be requested from our support if necessary. We are also fine with the community creating and maintaining their own docker container for the server, if so desired.

Originally posted by Sm91cm5leU9mQmVpbmc=: the funny thing is that you need to add one line to get rid of such issues, but as I see it, it has not been fixed since the "introduction" of the need to link an account. thanks to the developers for their support

That makes sense and I have suggested this change to the respective team. The required command line arguments for starting Eco servers were published in the respective Update notes and can be found on the wiki, though and the usage of docker compose files should be common knowledge to anyone using the container, given the audience it is intended for as a unsupported product.
