XF 2.2 tested different SMTP server, switched back, now no emails send!

I have a really strange issue with the email sending / Email transport method .

For almost 3 years we have been using SMTP:com and it was all set, now I wanted to test a new service (mailjet) so I changed the configuration of the SMTP to mailjet but no email went through. After no emails were send I switched back to SMTP.com with exact same settings, but now it does not send emails neither!?

What is wrong, do I have to clear some cache or do anything... it is really strange and I don't understand it.

I took a screenshot of the smtp.com settings before I did anything, they are exact the same.
