Let's encrypte on proxmox

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: cohenfamily.ch

My hosting provider, if applicable, is: One.com

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): proxmox server

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 2.1.0

Hello thank you to accept me in this forum.

I recently install a new server proxmox in my home lab to replace my old synlogy.

So it little challenge for me i'm not really confortable with this tool.

Those step already did.

1- my domain is cohenfamily.ch and i test it in this site is working:
Dig (DNS lookup).

2- i verify thice and the port 80/443 and port 8006 are open.
3-i'm able to connect like this https://prox.cohenfamily.ch:8006/
4-nginx is already install on proxmox directly not in vm

i'm juste note able to create my own certificate with let's encrypte in proxmox server.

I get that message when I try to do it:

Loading ACME account details
Placing ACME order

Getting authorization details from 'https://acme-v02.api.letsencrypt.org/acme/authz-v3/357754376432'
The validation for prox.cohenfamily.ch is pending!
Setting up webserver
TASK ERROR: Failed to initialize HTTP daemon

can you help me to follow some step ?

Looks like it tried to start a new webserver but failed because control panel already sits on port 80?

The easiest option for https in proxmox is to use the ACME support built-in. Certificate Management - Proxmox VE
