Thread: One specific user cannot login

We have one particular user getting "Login Failed" when trying to login. It is reproduceable. We can see the user is successfully authenticating in our Dovecot IMAP logs, however, we see the following in the Roundcube errors log:

Can someone please explain this error to me, and hopefully how to resolve this?

Thanks,
