Error adding a domain name to Let's Encrypt

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...

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 ..

.. 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/

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.
