Dedicated server crashing to desktop

[cpy]

I have a dedicated server that have been working for years I only update version or mods or change map but always was working.
Suddenly it does not start on clean install with or without mods. I can run same mods and save file on steam version but dedicated version does not start.
Any ideas why perfectly working server refused to work?

I tried loading different saves but still nothing even though I can load it in single player no problem on my main PC.

Also server stopped working after normal save game when I exited game to do planned restart of server but it didn't came back on. Just loading then crash to desktop.

Can you post factorio-current.log from a failed startup attempt? There are some issues with SE/K2 updates this week, if you have either of them installed.

I checked log and it says I have to verify login with email. The hell how do I disable email verification? I can't have my dedicated server randomly crapping out because of this!

How do I disable email verification? I'm not entering email every damn time I want to run my game!

Sorry about that! We added email authentication a few months ago to stop account takeovers. It can trigger when an account didn't have activity for a while or the password was found in a data breach. (You can check if the latter applies to you by logging into factorio.com)

You can avoid email authentication by saving your authentication token instead of your password in server-settings.json (See also https://wiki.factorio.com/Multiplayer#A ... figuration)

Will use token instead now. Thanks.
