Let's Encrypt SSL(Proxmox/pfSense) - Debian 11

I purchased a dedicated one at OVH, installed proxmox, it has a dedicated ip, I created a vm with pfSense, this one has another dedicated ip, on promox I created another virtual machine with ispconfig, it receives all the connection through pfSense, and I performed the releases of the ports, and this one I put the lan and wan card. I performed the complete installation.

My problem is that Let's Encrypt SSL doesn't enable it at all in this environment and I've researched a lot and haven't seen anything similar or a way to solve it.

 

Thank you very much!
The problem was solved exactly with this tweak.
"When your server is behind a NAT router or a firewall so that the server itself can not reach the hosted domains, then enable the option "Skip Letsencrypt check" under System -> Server config -> server1.example.com -> Web."
