My domain is: no domain, just server IP: 18.104.22.168
I ran this command: I do not run any commands. I have qnap server, i simply click on “renew certificate”
It produced this output: authentication failure, check dns or if port 80 works
My web server is (include version): QNAP 4.3.4.0752?
The operating system my web server runs on is (include version): QNAP 4.3.4.0752?
My hosting provider, if applicable, is: none, its a physical server in the company.
I can login to a root shell on my machine (yes or no, or I don’t know): Yes, I am administrator and can log in, I am the only one that takes care of the server, I once got Lets Encrypt certificate, can’t remember how, now it won’t renew on itself.
