Help, please! I cannot get certificate for Zimbra

Dear JuergenAuer! Thank you for answer.

Can you check my server again? I stopped Apache, maybe server not working for that? Now I restart all and ask you, please try check connection again.

I want to renew certificate today, but my sudo writting: “sudo: certbot: command not found”. I havn’t certbot or anything yet?

With best regards, Raulina
