Hi @avlza

that url

http://arnievlz.com/.well-known/acme-challenge/RoPgDgKWlfdyoTUnbXKvmw_foR61cpFJF1uwBuSQp50

doesn't answer, there is a timeout.

A working port 80 is required if you want to create a certificate via http validation.

I will update the port via plesk?

Welcome to the Let's Encrypt Community

Your webserver is currently non-responsive over port 80 http (as well as port 443 https). You need a functioning webserver that either responds to requests over port 80 or forwards those requests for response.

Did you shutdown your webserver for some reason?
