I am not a networking expert, so please forgive any poor or unclear terminology here . . .

My recently built Unraid Plex/Arr box works great, but I would like to set up NGINX Proxy Mgr and reverse proxy. My current challenge is that when I install NPM, all of a sudden all of my Arr apps, which are set to network though OpenVPN-Client, start mapping 443>443 and 80>80 (app to host).

Sonarr, Radarr, Readarr, NZBGet, qBittorrent, Bazarr, Requestrr all have app-to-host mappings like this, when NPM is installed:

Network: container:OpenVPN-Client

Port Mappings:

10.0.1.99:443/TCP10.0.1.99:443

10.0.1.99:80/TCP10.0.1.99:80

10.0.1.99:81/TCP10.0.1.99:81

My OpenVPN-Client app-to-host mappings don't include either port, which makes this doubly confusing:

172.17.0.2:3579/TCP10.0.1.23:3579

172.17.0.2:4545/TCP10.0.1.23:4545

172.17.0.2:6767/TCP10.0.1.23:6767

172.17.0.2:6789/TCP10.0.1.23:6789

172.17.0.2:6881/TCP10.0.1.23:6881

172.17.0.2:6881/UDP10.0.1.23:6881

172.17.0.2:7878/TCP10.0.1.23:7878

172.17.0.2:8080/TCP10.0.1.23:8080

172.17.0.2:8191/TCP10.0.1.23:8191

172.17.0.2:8989/TCP10.0.1.23:8989

172.17.0.2:9696/TCP10.0.1.23:9696

NGINX Proxy Manager network and mappings:

Network: br0

Port Mappings (App to Host):

10.0.1.99:443/TCP10.0.1.99:443

10.0.1.99:80/TCP10.0.1.99:80

10.0.1.99:81/TCP10.0.1.99:81

And, when I remove NPM, everything goes back to normal and works fine, with no app-to-host mappings showing up for Arr apps in the main Docker view.

What dumb thing have I done?

OpenVPN-Client is running normally, per its logs and ifconfig.me. The vpn.ovpn and vpn.auth files are working properly.

In the Extra Parameters field of Deluge template I have added: --net=container:OpenVPN-Client

In OpenVPN-Client template:

 - Network Type is set to None
 - I have added a port record: Host Port 8112 and Container Port 6881

Deluge's WebUI won't load at all. I tried qBittorrent instead, using the same approach as above, and it won't load the WebUI either.

For a couple of years, I have been serving Plex to a few friends and family from an NVIDIA Shield Pro on a gigabit fiber. Before that, I served from a Raspberry Pi.

I have basic Linux skills, and my dream is to build a more automated setup. Unraid OS with Plex and -arr apps looks great to a non-expert like me.

So, I just picked up an unmolested original Lenovo ThinkCentre M710Q 7500T with 16GB RAM, and a 256GB M.2. I have a spare 2.5" 2TB Samsung EVO 970 SSD that I could put in it; I also have a 3.5" WD Red 4TB external HDD.

Here are my questions:

• Do I need more RAM to be able to serve four 1080 streams at once?
• Should I use the SSD or HDD, or both?
• Any other advice or suggestions? It's appreciated!

I started with XMBC then Kodi then Plex on a succession of Raspberry Pis. Then, four years ago, I switched to running Plex on a Shield Pro.

Now, I am trying to pick up enough Linux and Docker knowledge to be able to set up a Plex server, just for video, with automated RSS torrent management, running in Docker on an 8GB Raspberry Pi 4 running Raspbian Bullseye.

I am not a technologist by trade, so hoping to find a Docker image that enables that without needing a lot of additional Linux plumbing to make it work. I am old and mostly rely on rudimentary UNIX skills left over from the late-'80s.

Thanks for considering!

I am at a high-beginner/low-intermediate level in Python, and one thing that drives me nuts is how poorly I am able to read the Python official documentation and grok how to use the described code.

What's the secret? Are there any guides/videos/books that can help my understand how to approach reading it? Or, is it just one of those things that I need to just keep coming back to while coding, and eventually I will get the hang of it?
