My domain is:
avb-formularios.inappsis.com
I ran this command:
sudo certbot --nginx -d avb-formularios.inappsis.com
It produced this output:
Challenge failed for domain avb-formularios.inappsis.com
Timeout during connect (likely firewall problem)
My web server is (include version):
Nginx 1.7.10
The operating system my web server runs on is (include version):
Ubuntu Server 24.04
My hosting provider, if applicable, is:
Self hosted
I can login to a root shell on my machine (yes or no, or I don’t know):
Yes
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):
v0.40.0
Problem:
I’m trying to issue a certificate for the described domain. I’ve disabled ufw to make sure Let’s Encrypt has access to the well-known path. Right know I’m testing with this path:
http://avb-formularios.inappsis.com/.well-known/acme-challenge/1234
Although I have access to that challenge, Let’s Encrypt is failing to validate the challenge.
I also tried the standalone validation but it’s not working (same timeout error):
sudo certbot certonly --standalone -d avb-formularios.inappsis.com --dry-run
