[2022] No response from auth server

What is the exact error you are getting, "Our auth servers may be down"? In that case make sure to check any security software, firewalls and your ISP and make sure Eco is exempted, something is blocking the connection to the authentication server.

In Eco the server does the authentication for a valid license, a local singleplayer game just starts a local server, which will do the check the same as on dedicated servers for multiplayer. So if your PC is not able to connect to our authentication server, your local server will not be and you cannot connect - while at the same time you might be able to connect to dedicated servers without issue, given they do not have a connection problem to the authentication server.

Seems you have already resolved it though, happy playing :)
