The server could not connect to the client to verify the domain; I can connect


Please fill out the fields below so we can help you better.

My domain is:

I ran this command: certbot certonly --non-interactive --agree-tos -m --webroot -w /html -d

It produced this output: main :: Could not connect to

My operating system is (include version): ubuntu

My web server is (include version): using webroot

My hosting provider, if applicable, is: NA

I can login to a root shell on my machine (yes or no, or I don’t know): yes


Hi @cwalv

I can’t connect to on port 80 but I can on port 443, so yes, seems a firewall issue or a webserver misconfiguration.
