guac-install VS docker-webtop

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

Or, install https://github.com/linuxserver/docker-webtop on the remote server and then use a GUI library manager in that container, if you really need a GUI.

I've also run a Minecraft server on that mini pc and it ran just fine, but if you want to host more games there are other more powerful machines you could use. There are also a whole world of other services you could try. I've been enjoying Webtop lately, for example.

You could spin up something like Kasm Workspaces, Neko or Docker Webtop.

Install docker and docker-compose. You can search docker-compose HERE and then docker-compose pull and docker-compose up -d

After i had a look at Kasm Workspaces and found it a bit too heavy for my use-case, i was trying to setup a simple linuxserver/webtop container.

Someone on Discord recommended I spin up a Webtop Docker container but they weren't too sure if this would let me login with multiple users. These containers, to my understanding, run their own versions of Guacamole, so managing each of these instances could get complicated over time.

you could just use webtop (https://github.com/linuxserver/docker-webtop)
