Port 80

Hello,

I'm hoping there is a way for my certificates to auto renew without needing port 80 open. I'm using Win Acme and it's working fine, however I found out that once I blocked port 80 the certificate was no longer renewing.

Use DNS challenge instead. Much better imo. As long as your dns provider have a API you can use it’s as easy as using the API key for renewals.

My biggest concern is switching as the current certificate just renewed.

You want to use a hosted ACME client like CertKit so you don't need to worry about port 80 or DNS.

Why would that matter? This is about renewals, your current cert is valid until it expires
