I haven't had any issues generating certificates since I first started using Let's Encrypt last August or September. Trying to renew now I am getting the message below.
I haven't changed ANYTHING in my setup. I know the port forwarding is working because I tested with PLEX and it connects just fine from outside the network.
I am running on a MacMini using macOS Monterey. I'm using ONLY as a mail server.
I have ports 80 and ports 443 being forwarded to the MacMini.
All help is greatly appreciated!!
Certbot failed to authenticate some domains (authenticator: standalone). The Certificate Authority reported these problems:
Detail: 220.127.116.11: Fetching http://ellegard.net/.well-known/acme-challenge/R37Bk8-ml-m2H6_fOjKPmjwX6B6yWO67ejfOe3Bah5o: Timeout during connect (likely firewall problem)
Detail: 18.104.22.168: Fetching http://widenett.com/.well-known/acme-challenge/uRo3RONJlh4BWc3Ng0YWNTt8TanwFElGhvkevkdB2i0: Timeout during connect (likely firewall problem)
Hint: The Certificate Authority failed to download the challenge files from the temporary standalone webserver started by Certbot on port 80. Ensure that the listed domains point to this machine and that it can accept inbound connections from the internet.
Some challenges have failed.
