My domain is:
I ran this command:
It produced this output:
My web server is (include version):
The operating system my web server runs on is (include version):
Fedora server 31
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know):
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you’re using Certbot): certbot 1.5.0
when I connect to my (IMAP) mail server running dovecot-220.127.116.11-1.fc31.x86_64 I get an error stating that the cert for the server has expired, even though I’ve confirmed with certbot renew that all certs are up to date. Any help would be greatly appreciated
Was Certbot configured to reload/restart Dovecot after the certificate renewal? Have you tried reloading/restarting Dovecot manually?
The cert doesn’t look expired to me, are you sure it’s complaining about the IMAPS certificate?
$ openssl s_client -connect imap.eccentric.dk:993 -showcerts | openssl x509 -noout -dates

imap.eccentric.dk:993 is valid.
eccentric.dk:993 there is the same certificate - see https://check-your-website.server-daten.de/?q=eccentric.dk#connections - so this certificate is invalid, the name doesn't match. But there is no expired certificate visible.
