My domain is: febos.ddns.net
I ran this command:
sudo certbot certonly --webroot -w /mnt/NoChill/apache_server -d febos.ddn s.net
It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log Requesting a certificate for febos.ddns.net Certbot failed to authenticate some domains (authenticator: webroot). The Certificate Authority reported these problems: Domain: febos.ddns.net Type: connection Detail: Fetching http://febos.ddns.net/.well-known/acme-challenge/qKqIBqJ0yYhY9Sv_7MJU3zD8dVfUZ8WJ6lDzF2VEUnI: Timeout during connect (likely firewall problem) Hint: The Certificate Authority failed to download the temporary challenge files created by Certbot. Ensure that the listed domains serve their content from the provided --webroot-path/-w and that files created there can be downloaded from the internet. Some challenges have failed.

My web server is: Apache/2.4.41 (Ubuntu)
The operating system my web server runs on is: Kubuntu 20.04
I can login to a root shell on my machine (yes or no, or I don't know): The server runs on my laptop so this is unnecessary I guess (?)
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you're using Certbot): certbot 1.18.0
As the title goes. I can access the server fine from my browser but certbot throws timeout.
I am positive that it's not my firewall because I have tried the url from my phone using cellular data. I even tried manual mode and accessed the exact same link from my phone without any trouble and yet certbot timeouts for some reason.
I also tried the --apache flag and the result is the same.
The hint is a bit misleading though. It shows the same hint even if I don't create the file - which suggests the server can't actually establish the connection in the first place. I have tried everything and out of options now. Please help!
[I will keep the server running for next few hours in case anyone want to check]
