I put in a ticket also, but figured I would also post here.

I am attempting to run Plex Media Server on my unraid box.  But after finding issues with Plex confirming my Plex Pass membership, I discovered it was having issues with it's dns resolution of metadata.plex.tv

My main PC can see it just fine and has no issues.  The unraid server is the only thing on my network having this issue. I run a UDM SE and have the dns setup for 1.1.1.1 and 8.8.8.8

I run dig and see this:

root@Tower:~# dig metadata.plex.tv ; <<>> DiG 9.20.8 <<>> metadata.plex.tv ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 8147 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 1232 ;; QUESTION SECTION: ;metadata.plex.tv.              IN      A ;; AUTHORITY SECTION: plex.tv.                1800    IN      SOA     jeremy.ns.cloudflare.com. dns.cloudflare.com. 2384298523 10000 2400 604800 1800 ;; Query time: 7 msec ;; SERVER: 1.1.1.1#53(1.1.1.1) (UDP) ;; WHEN: Thu Sep 25 15:19:16 PDT 2025 ;; MSG SIZE  rcvd: 109 

I tried using copilot to help resolve this and it just kept putting me in circles changing my DNS provider and never solving the issues. Unraid seems to be hitting other things. My reverse proxies are working. For some reason, it is having issues with metada.plex.tv.

I know there is nothing wrong with that link since I can hit it successfully from the rest of my network. I have reset my UDM and my unraid server to make sure things weren't cached. Nothing seems to work. Plex is also running it's network in Host mode.

Try booting with a new flash drive using a stock install, no key needed, then using the default settings, see if you can ping that address. That should confirm if it's an Unraid config problem or an external issue.

I started an answer on configuring plex through reverse proxy as i struggled to set it up. but i don't think it's necessary.

Does your server runs correctly ? Is it accessible from the outside and the inside ?

If yes where is the trouble?

FYI i can't resolve metadata.plex.tv neither. And when you like online at dns stuff, dns tools,... there is no record for metadata.plex.tv

I wonder how your pc can resolve it.

Perhaps its just some weird thing from plex which should resolve locally like their plex.direct links.

For the previous person, I did create a new thumb drive and started it up and had the same results with the new version of Unraid.

Yes my plex is accessible outside my network. Everything else works fine with plex. It just can't get metadata or confirm that it's a Plex Pass subscription.

This is very frustrating and literally the only reason I actually purchased Unraid.

Yeah I don't know exactly what they were doing with those URLs, but the work in a very certain way. There is plenty of documentation on that.

nslookup metadata.plex.tv also fails for me, and I don't have any DNS issues, so lçooks like that is normal and not related to the problem you are having, look for the support thread for the Plex container you are running; you can find it by clicking on it and then "support"

it looks like you don't have your server linked to plex servers.

you should look at this link

My server is certainly linked to the plex servers. It has been claimed, I even had to remove the claim and reclaim it to test. That is not it.

Literally I have run Plex on multiple server os's and this is the first OS that has caused issues. The unraid support was just plain unhelpfull so I am just going to ask for a refund and go to a better OS that doesn't have issues. It's funny that they say it's a plex container issue when that same plex container works in every other OS.

Like already mentioned, metadata.plex.tv doesn't resolve a DNS, if you are having issues with Plex, that is not the reason for the problem, and Unraid support likely won't be able to help with configuring 3rd-party apps,
