Won’t let me play my own media on LAN

I host Plex Server on my Synology NAS, and have used a Plex Pass for years to reliable access my library on my network.
I often use Chrome as the player since I use a profanity filter for my kids.
Navigating to plex.tv has allowed me to access my media until tonight, at which point I was told I need a Remote Access subscription, even though I am on my LAN.

I accessed plex directly by IP and it worked.

This leads me to believe there is a bug in the routing of app.plex.tv which is forcing it to route externally rather than work with a local network.

Has anyone else seen this, and how do I fix it?

Can you please Stop the server.

Using FileStation

  1. Navigate to PlexMediaServer/AppData/Plex Media Server (DSM 7)
    -or- Plex/Library/Application Support/Plex Media Server (DSM 6)

  2. Right-click LogsCompress to Logs.zip

  3. Download the ZIP file

  4. Attach it here.
    We should be able to see if PMS is having any network / DNS issues.

Thank you for the reply. Which file specifically would be helpful for you? The logs contain my email and movies, so I don’t want to make that public.

The information @OttoKerner mentioned did lead me to check into my router. It turns out that the ASUS ROG AX11000 apparently has DNS rebind protection enabled by default, with no GUI option to change it, so I set

rebind-domain-ok=/plex.direct/

via an nvram update through SSH.

Unfortunately, even with my default router of 192.168.50.1, Synology NAS of 192.168.50.153, and macOS ip of 192.168.50.123, I could not get it to perform a successful

nslookup of 192-168-50-153.plex.direct

It posts back with:

Server: 192.168.50.1

Address: 192.168.50.1#53

Non-authoritative answer:

*** Can't find 192-168-50-153.plex.direct: No answer

I disabled remote access in plex.tv, and as expected lost access to my NAS, which is named RARE-STORAGE

I then opened PMS on my NAS directly, and enabled remote access as RARE-STORAGE.local in which case it lets me use it at that address.

The problem is I need to access it via plex.tv, which to my understanding should have the routing logic to know to resolve plex.direct and access my local IP’s.

The reason I need it is I use the Advanced Profanity Filter plugin to remove profanity. I may work on adding a filter directive for it with rare-storage.local though and see if I can get working.

If you have any ideas for getting plex.tv to work again locally for me, I appreciate it.

Also, I can send you the log files directly if you have a way. I just didn’t want to make it public.

I figured it out.

macOS was blocking Chrome from traversing the local network.
System Settings > Privacy & Security > Local Network > Chrome

I wish I had found this prior to a full preference uninstall of Chrome, profile deletion, reinstall, maOS reinstall, etc. LOL

Live and learn! Hopefully this helps someone else.

Good to know that app.plex.tv has a local router call, and the client browser / OS resolution does play a part.
