I don’t understand why it’s necessary to have port 80 open to renew a LetsEncrypt certificate, particularly if the certificate has not yet expired. So every few months I have to unblock port 80 on my firewall so that I can renew the certificate. What’s the reason for this restriction?

Renewing via port 443
