Hi all
Really hoping to get some advise here!

I was using Thunderbird as a email client and all worked great until a few days ago, the stopped working and said the server cannot be reached and that there are authentication errors.
Al the settings are still fine and my emails work 100% on my phone when on mobile data but as soon as i switch to wifi it wont connect to the email server.
I logged into my mail from chrome browser from the same pc and it works 100%

I tried EM Client as well but the same issue, authentication failed.

Any feedback/advise will be appreciated!
