I have an Ubuntu server with a website and a setup with postfix, dovecot, and roundcube.
All was working well. But this week, I have extended the wordpress website from 1 single-site to 6 sites (multisites). As such, I extended the CertBot certificate with the new domains.
In order to do this, I added virtualhosts to /etc/apache2/sites-enabled/domain.com.conf. I ran the certbot command for the domain. It worked well. But I have also "locked" myself out of my postfix/dovecot/roundcube it seems.
Now, when I enter to log in. I go mail.domain.com/mail (Only works without https:// now).
And I try to log in as normal. But it tells me that I cannot connect to the email-server.
When I login on my phone it tells me
Connection to IMAP server failed
.
In mail.log I get the following error:

In roundcube errors.log I get the following error:
