If the HOA’s router supports UPnP/NAT-PMP/PCP then you might be able to use that to get some ports forwarded.

Is it possible to send the hint from OPNsense itself?

Yes, to me it sounds like you’re already getting a big enough prefix from your ISP (all devices getting a /64), but you’ll have to request a bigger prefix from OPNsense. I believe it should give you the options to do this when you set the IPv6 mode to DHCPv6 on OPNsense, but I can’t say if your ISP router will handle it.

I have also added all Cloudflare IPs in Jellyfin’s known proxies

You should only need to add the IP of the last proxy before reaching Jellyfin, which would be Caddy.

If you can’t get the VPS to work, alternatively there’s Cloudflare but last I checked streaming was a little out of their free terms. With it, you should just have to set your AAAA record and make the cloud orange, that way Cloudflare will proxy it, and IPv4 will work. There’s also Cloudflare tunnels which lets you host websites without port forwarding anything.

then there’s definitely the type of water ditching where the plane angles into the water at full speed, and I don’t think that’s gonna have 80%

Pretty sure last time that happened it was still ~30%, which seems pretty impressive considering the video: https://youtu.be/w1u0D0E-Bq0 (SFW but it is a plane crashing)

I’ve got a catch-all setup to go straight to my spam folder, OP could do something similar.

My AMD Laptop has USB 4, which is effectively the same AFAIK.

That’s not really your code, more so you haven’t setup a .gitignore to not commit not your code.

I’m probably jumping to conclusions, but Nvidia?

Firstly, there actually isn’t much difference between server grade and gaming motherboards, like sure one might support ECC + IPMI and the other RGB + overclocking, but as far as compute goes, they are both effective motherboards.

Secondly, I don’t think OP was going for a ‘server’ but more of just a workstation type build, so why one or the other?

Thirdly, why does it even matter? OP should be proud of their system whether you like it or not. Even if they are using it as a server, my first server was just some reasonably priced consumer grade parts and I never had any sort of stability issues with it.
