my Let’s Encrypt cert has expired and I wanted to renew it.
Unfortunately, I now get an error message and don’t know what the problem could be.
had it installed with certbot and so far everything has worked, now I get this error message:

Additionally, please check that your computer has a publicly routable IP address and that no firewalls are preventing the server from communicating with the client. If you're using the webroot plugin, you should also verify that you are serving files from the webroot path you provided.
Firewall is open to Port 80 and 443 and pointing to the server IP.
DNS AAA is entered correctly and points to our correct public IP.
