I have IPMI and web interfaces for most gear, I just don't want to have to carry a laptop in every-time I need to tinker.
I also have a bunch of AV switchgear and it would be handy to adapt a multiviewer to one of the VGA ports for monitoring that side of things too.
the Arr apps will automate downloads but you can go into their ui's manually for overriding things when needed (like replacing a bad copy of a TV show for example), jellyseer/overseer handles requesting and adding new shows/movies to be monitored from a simple webapp that you would host on the server and give them a shortcut to on their devices homepage.
I'd go with a 12th gen or newer intel cpu, something small and entry level is more than enough like a 12100 or 12400, we just want the igpu to handle the occasional transcode, 16gb of ram, a cache SSD or two in a mirror, and a decent stack of HDDs of your choice, the OS can be anything you want but I suggest going with something NAS focused like unraid, openmediavault or truenas (jellyfin is not officially supported on truenas but it does work). if it's a new build from scratch for long term archival of high quality media i'd start with at least 6 HDDs, with one for parity, if you can budget for 20tb drives for example that gives you a spacious 100tb of useable space with the ability for any one disk to fail without any data loss. you can then build that into a normal ATX PC case.
You can use windows or any flavour of linux but you will be doing more work to make them work properly, where the above solutions are more plug and play.
I would make sure their hardware is capable of playing as many file formats and codecs directly as possible though, when you get into hosting 4K media, particularly for full fat UHD Bluray rips, you will find apps built into TVs or lower end streaming boxes just cant do it and the server has to chug through transcoding on the fly, the igpu can do it just fine, but you should try to avoid it for maximum performance and image quality, so perhaps budget for an nvidia shield or something.
Plenty of players still don't support AV1, though with a modern gpu you can brute force transcoding it on the fly.
I have a jellyfin test server running an an intel n95 and it can easily handle a couple of 4k AV1 to H265 transcoded streams on it's own with decent image quality, but it struggles with 3 if the bitrates are too high. still, it's more complexity than is needed considering AV1 only saves a small amount of space over a good H265 encode which are ubiquitous on the net.
I put of grabbing one of these when my work was clearing them out, giving them away for next to nothing.
Now when I actually need one I cant find one for less than the cost of my best damn server. and nobody seems to make a basic cheap one.
I don't think he's enough of an asshole to admin that instance.
You can get banned there for sneezing the wrong way.
Hell I once got banned for talking about being banned.
Is it related to this issue posted to the bsd forks github?
I cant help you directly as I run Jellyfin on linux, but that should be your first port of call. just keep in mind jellyfin on FreeBSD is 100% unofficial so you are on your own.
For maximum compatibility with all services you are limited in your choices due to DRM licence requirements.
You can mostly decrapify android based boxes via ADB to strip out much of the bloat, strip most of the telemetry entirely then block the rest in your firewall, and replace the launcher with a super barebones one like Flauncher but it will never be 100% perfect.
If you must be in full control of what is on the device and what it is doing, a small, low powered miniPC (intel n100 is a good chip for basic AV for example, 4k 10bit with perfect H265 and AV1 decoding) and use the operating system of your choice, but you are then limited in what you can stream via browser or third party apps, often in nowhere near full quality, again this is due to licencing and drm.
The best option is to avoid streaming services altogether and download your own content, then use an offline player like kodi or a server/client solution like Jellyfin (a free and open alternative to plex, with most of the base features well implemented) to play it.
I have an Onyx Boox tablet and use ubooquity as an ebook OPDS server on my unraid box at home, it has an online reader that's pretty good, but I just download the ebook file to local storage and use the much better reader built into the system. I'm a slow reader so I dont have to do it often.
I haven't really found a third party reader that is e-ink optimised and can seamlessly integrate an OPDS server. I'd like to find one, particularly if it has syncing between devices as I also use a foldy phone as my main device so it seems some use as a reader sometimes.
I also self host a huge archive of manga in Komga, and access that on the tablet and phone via a tachiyomi fork, it handles e-ink optimisation pretty well. It also doesn't sync between devices but if I use the komga web reader it does, it's just a bit power hungry on the Boox and has no offline functionality so I just manually keep in sync which isn't that hard.
Flauncher for absolute minimalism, or projectivy for a more featured replacement.
While it's unlikely your ISP is blocking all uploads on that protocol, a vpn would bypass that.
So a vpn is worth testing
What does your Docker port mapping look like?
Perhaps the port is open and forwarded in the router but not getting through the Docker network? Are you mapping 1:1 or using different internal/external ports?
There are a few models available with 1920x1080 displays, but they are mostly still 4:3 screens and VGA inputs.
