Cannot connect to server unable to execute pop3 command

Hi Since yesterday I cannot get my emails from my account on my Android phone.
I get the error ‘cannot connect to server’ (unable to execute pop3 command)
I can send emails though.
None of the settings have changed and I use identical settings on my pc with thunderbird.
Other email clients do work.
I have enabled logging but not sure where the logs are stored
version 5.806

Please see No POP3 email from IONOS/GMX - "Unable to execute POP3 command"
