[Installation] Timeout On Cert Verification Step of CA Generation

My domain is: kamailio.gcel-legc.ca

I ran this command: sudo certbot --apache -d kamailio.gcel-legc.ca

It produced this output:

My web server is (include version): Apache2

The operating system my web server runs on is (include version): Ubuntu 18.04

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

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot

It's possible it is a firewall issue but we have checked the rules and everything seems okay.

Hi @cam.d286

your output says: It's not ok. Find the blocking instance or a wrong router configuration.

Do I need an externally accessible webserver? Or is it simply just reaching out to the letsencrypt host and not getting a reply. Thanks for the reply!

Please read the basics:

Perhaps more specifically relevant here:

@cam.d286, in this case the certificate authority is trying to connect to your webserver over the Internet in order to confirm your control over the domain name.
