trying to obtain a certificate, on ubuntu 18.04 with nginx:
certbot certonly --nginx -d assistenza.setsnc.com
I get this:
Failed authorization procedure. assistenza.setsnc.com (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching http://assistenza.setsnc.com/.well-known/acme-challenge/0iAl5ckMvf9Kcuru9QocAm1np7whcFIvwWM4TwttVcQ: Timeout during connect (likely firewall problem)
Is port 80 open? Firewall? NAT router without a portmap?
read your output: A working port 80 is required. Your port 80 - https://check-your-website.server-daten.de/?q=assistenza.setsnc.com - has only timeouts.
So it’s impossible that Letsencrypt checks your domain.
thanks for your answer, I understood the error output, the point is that is not true: try to browse directly that address, and you’ll see…
Please: There is a timeout, with my browser, with the online tool. You may see your site internal or you have a firewall with regional blocks.
Yourr site is invisible. So http validation can’t work.
PS: The Letsencrypt error message is the same - Timeout.
