Tokens invalid?

[Civ01]

The tokens I'm getting in specific UE game and the tokens I request for same appID via SteamUserAuth do not match:

SteamUserAuth:

The game probably requests encrypted token, which I haven't looked into. What game? :)

[jesterret]

I don't have the game, so I'll have to see when I can check it out, but this config entry indeed states they encrypt client-server communication for the auth process.
What You'd have to do is to find the key they use for encryption (might be PlayerDataEncryptionKey, might be something in the code only), get the token with this library, then encrypt it with AES GCM and send that.
