I cannot set up my icloud email in Thunderbird.

Error implies that the password is incorrect but i know it's correct, i am able to sign in to webmail using it just to prove a point.

"Unable to log in at server. Probably wrong configuration, username or password"

I have verified server info on apple support and verified username and password is what i use on all other devices. Username and password also works on MS outlook.

Did you enable Two-Factor authentication and did you create an app-specific password before trying to set up an iCloud email account in Thunderbird?
