Em Client will no longer connect to Yahoo

Hi, (see end of post for addition edit)
A couple of days ago em Client suddenly started to not connect to Yahoo mail. No incoming mails nor outgoing mails.

I had NOT changed any settings.

The Diagnose tab’s Fix option could not fix the problem.

I have copied the log entries below.

Can anyone help!

Regards
Martin

I have just noticed that when I try to conect without my VPN running I get a different error regarding an ‘unexpected end of stream’ which I haven’t a clue about.
