My domain is: vps300.arconsult.hu
I ran this command: certbot renew --dry-run
My web server is (include version): Apache 2.4.25
The operating system my web server runs on is (include version): Debian 9.13
I am running my https site on port on port 9005, not 443.
Neither port 80 nor port 443 are open.
Dryrun completes fine without error.
Newbie Question: do I need to open port 443 and/or 80 for renewal?
Thanks for reply
Peter
