I finally managed to install certificate for Dovecot via gui and also i must install it for another domain of main being mail.superhost.gr
When i go to Let's Encrypt tab and insert the domain mail.superhost.gr there i get
Requesting a certificate for superhost.gr, www.superhost.gr, mail.superhost.gr, autoconfig.superhost.gr, autodiscover.superhost.gr from Let's Encrypt .. .. request failed : Web-based validation failed : Failed to request certificate : mail.superhost.gr challenge did not pass: Invalid response from http://mail.superhost.gr/.well-known/acme-challenge/ehjlhZ395d10M4mgRL50...

****mail.superhost.gr challenge did not pass: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.mail.superhost.gr****
Could someone please exaplin to me whay this happens and what step i need to take to fix it?
It turned out a DNS TXT Record was the problem, now i removed and now iam receiving this message:
Requesting a certificate for superhost.gr, www.superhost.gr, mail.superhost.gr, autoconfig.superhost.gr, autodiscover.superhost.gr from Let's Encrypt ..

Either wait 7 days or remove one of the hosts from the request so the the request isn't identical to the last one. And in 7 days put it back.
Which host do you think should i remove? Which one won't matter, if any?
superhost.gr
www.superhost.gr
mail.superhost.gr
Should i skip these two?
autoconfig.superhost.gr
autodiscover.superhost.gr

I try only these three. Requesting a certificate for superhost.gr, www.superhost.gr, mail.superhost.gr from Let's Encrypt ..
.. request failed : Web-based validation failed : Failed to request certificate : Error requesting challenges: Error creating new authz :: too many failed authorizations recently: see https://letsencrypt.org/docs/rate-limits/
DNS-based validation failed : Failed to request certificate : Error requesting challenges: Error creating new authz :: too many failed authorizations recently: see https://letsencrypt.org/docs/rate-limits/
It still has identified the attempt.
