guac-install VS guacamole-docker-compose

It maybe mine works because, you installed using docker and I used this guy's Guac install

I had it running in a Debian (9 or 10, it was a couple of years ago) LXC using this install script, maybe give it a try?

I'd suggest that instead of doing it on the base ProxMox install, do it in a debian 11 lxc container, using this install script that will do almost everything for you. You'll have to forward the public facing port from pmx to the lxc.

VPN, wireguard, blocking, chrome. I had a similar case and a perfect solution proved to be Apache Guacamole (https://guacamole.incubator.apache.org/). Absolutely clientless RDP/SSH access to any server with any common browser (HTML5). Works as a proxy for RDP/SSH (magic) Simple install on Ubuntu via https://github.com/MysticRyuujin/guac-install and an extra Nginx (see bottom of readme). Who needs OpenVPN anymore - I bet it cannot be locked down as long as you have the ubuntu public IP allowed.

I used the MysticRyuujin script to perform the upgrade and immediately had some issues based on an Ubuntu server 20.04.3 installation. No connections worked. The underlying issue is the guacd service listening on IPv6 and Tomcat working on IPv4.

However, I wanted to be able to access my guacamole instance remotely as well. I installed it using a script and have TOTP in front of it also, but I didn't like the idea of guacamole being accessible to the wider internet since it essentially has full access to my computers. I installed it a while ago in an LXC using this script.

I used the mysticryuujin's script here: https://github.com/MysticRyuujin/guac-install

Great software, this is the only guide I found which worked to install it with Docker. https://github.com/boschkundendienst/guacamole-docker-compose

https://github.com/boschkundendienst/guacamole-docker-compose Uses the official images so its more up to date.

I started following the guide/setup available in this github: https://github.com/boschkundendienst/guacamole-docker-compose and got the whole thing up and running.

I have guacamole with docker (https://github.com/boschkundendienst/guacamole-docker-compose) and it comes with an nginx container installed, with a cert already done, seems to be using a reverse proxy also, so when I try to use an apache reverse proxy (use apache on my server) it says " Error 526" Invalid SSL Cert. Does anyone know how I can modify this so I can use my own domain?

Using Docker, with docker compose, I used the following github repository, https://github.com/boschkundendienst/guacamole-docker-compose, to set up my own Apache Guacamole webserver. It automatically sets up a reverse proxy with NGINX and everything is working perfectly. However, now that I want to expose Guacamole to the web, I want to use Let's Encrypt to get myself a certificate (I have a working domain), however I am not sure how to to generate the certificate files using Certbot as directed on their website for NGINX running in a docker container.
