I’m guessing the cloudflared daemon isn’t connecting to jellyfin. You want to use http://. Also is jellyfin the hostname of the VM? Using localhost or 127.0.0.1 might be better ways to specify the same VM without relying on DNS for anything.

Personal opinion, but I wouldn’t bother with fail2ban, it’s a bit of effort to get it to work with cloudflare tunnel and easy to lock yourself out. Cloudflare’s own zero trust feature would be more secure and only need fiddling around cloudflare’s dashboard.

Consider something like the aoostar R1 with Intel N100. Small and low power like a commercial consumer NAS but cheaper and you can chuck whatever OS you want.

Would you consider making the LLM/GPU monster server as a gaming desktop? Depends on how you plan to use it, you could have a beast gaming PC than can do LLM/stable diffusion stuff when not gaming. You can install loads of AI stuff on windows, arguably easier.

I’ve been using pcloud. They do one time upfront payments for ‘lifetime’ cloud storage. Catch a sale and it’s ~$160/TB. For something long term like backups it seems unbeatable. To the point I sort of don’t expect them to actually last forever, but if they last 2-3 years it’s a decent deal still.

Use rclone to upload my files, honestly not ideal though since it’s meant for file synchronisation not backups. Also they are dog slow. Downloading my 4TBs takes ~10 days.

My 10 year old ITX NAS build with 4 HDDs used 40W at idle. Just upgraded to an Aoostart WTR Pro with the same 4 HDDs, uses 28W at idle. My power bill currently averages around US$0.13/kWh.
