I think I know why this error occurs on my system. I recently got a message from Google that they won't allow third-party apps that only require a username and password and use SMTP technology to use Gmail. They recommend using apps that allow you to sign in with Google, which TripleA can't do at the moment as far as I know. Can this be changed in future versions of TripleA?

I wonder if that is related to this https://forums.triplea-game.org/topic/3061/marti-issues/19 or this https://forums.triplea-game.org/topic/3148/dice-server-registration-not-working

@beelee1

Likely not. This issue is about an error that occurrs if you have not allowed "less secure apps" in the security settings of your Google account. When PBF TripleA acts like a mail-software that sends mail. Google requires the named setting in case you send mails with Google mail accounts with "No-Google"-software.

Accidentally closed, so reopened.
