Yeah I'm not defending it, just doubt it was intentional, hopefully they sort their shit out. The fact that it's a GoDaddy project bouncing you isn't a great sign of that.
Probably just over zealous ddos protection. It's often a balance of a few false positives in order to keep the site online.
If a controller is still connected (Bluetooth?) it may be a controller order issue, you can try reordering them.
No, the browser would still send YouTube.com as the host header. While yewtu.be could be configured to allow this to work, the TLS cert would not and the browser would get upset.
Also the alternator absolutely takes more power from the engine in proportion to how much energy it's putting out.
Jellyfin is very conveniently packaged in docker, so while it may seem daunting, I highly recommend at least trying that route.
Running an nfs mount, docker or not, should be perfectly fine. Jellyfin just uses normal storage so won't care if it's nfs. No real special considerations with proxmox either, especially without worrying about a dedicated GPU. Just spin up a Debian guest and go.
Fortunately that's not how it works when you have all the access points controlled centrally, like with unifi. Yes there is limited frequency space, but this is much less of an issue on 5ghz. There will also only be one ssid, and handoff between access points is pretty seamless.
3-4 is probably overkill, but the attenuation situation sounded pretty dire. I run two in my house for redundancy mostly, just standard American stud and drywall construction.
If you have the ability to easily add wires, I would go with a system that allows you to wire everything together, rather than depending on a purely wifi mesh. Personally I'm running unifi ceiling mounted access points for this. They run on power over Ethernet, so you just need to get one cable to each. You can control them with their free software controller if you are into that, or something like their dream router.
Run 3-4 of those access points placed throughout the house and you'll never have a weak signal again.
Kayak is a clc shearwater sport that I built in my basement.
Try booting something different on proxmox like an ubuntu live desktop, just to make sure networking is working there. Seems like haos can't talk to the Internet.
