Just because the destination IP address is not a LAN address? That’s not misconfiguration, that’s a legitimate use of NAT reflection/loopback. If that’s how it determines who is streaming remotely then just run it behind nginx that forgets to set the correct headers.

Edit: Apparently Plex centrally relays all the traffic? Self-hosted my 🍑, it’s not self-hosted if you need to rely on their server.

I only ever opt for RAID 5. It also help to use error correcting hardware.

Yeah, 5TB for every register of course.

If apocalypse is another word for thursday…

I explained why. Misconfiguration and caching.

You would also need to clear your device’s DNS cache.

Not two A records. From what I understand, OP has an A record pointing to their public IP address (which Nginx is listening on behind a NAT). Then, on the local network, OP uses their own DNS server to ignore that entry and instead always serve the local IP when a host on the LAN queries it.

Aside from OP’s devices potentially using a different DNS server (I was only able to solve it for my stock Android by dropping outgoing DNS in my firewall), this solution is a nightmare for roaming devices like mobile phones. Such a device might cache the DNS answer while on LAN or WAN respectively and then try to continue using that address when the device moves to the other network segment.

These are the most likely scenarios in my opinion - OP’s devices are ignoring the hacky DNS rewrite (either due to using a different DNS server or due to caching) and try to access the server via the public IP. This is supported by the connection timeout, which is exactly what you would see when your gateway doesn’t do loopback.

Never point your DNS at two different IP addresses like this. It will only cause you pain and unexpected behaviour.

What you are experiencing is solved by so-called “NAT reflection” or “NAT loopback”. It’s a setting that - in the optimal case - you should just be able to activate on the appropriate interface on your gateway.

If you do not have that setting or do not have access to the edge router, but only some intermediate router, you can do a nasty hack. You can point static routes to your public IP address to point at your local IP address instead. In that case, you also need to tell your server to accept packets with your public IP address as the destination.
