"New" router, now Plex server not working properly

[wanstronian]

Hi folks,

A few days ago, after a series of power cuts, my trusty old Billion Bipac router decided to commit suicide. By chance (long-ish story) I had an unopened Asus DSL-AC68U kicking around, so I unplugged the Billion, plugged in the ASUS, and was back up and running.

Or so I thought.

I'm now finding that my Plex server, which runs in a Jail on my TrueNAS Core machine, is unreachable from the Plex client on my Fire TV stick.

I can access the UI from my browser, but not from Fire TV stick. I also noticed, when doing a rescan of my Movies folder, that the scan took ages and the thumbnail was broken. When I enter a MoviesDB URL, it fails to download the resource.

Nothing has changed on the Jail.

All of which leads me to believe that something on the new router is blocking the Plex Server. I've tried setting up port forwarding for the Jail's IP but it hasn't made a difference.

Before I give this up and consign the Asus to the bin under the heading of A Bad Purchase - can anybody help me understand what the problem might be?

It may help if you post some more detailed information on how exactly you have configured the router.
Are the NAS and the FireTV stick on the same network subnet (ex: 192.168.1.x)?
Is the FireTV connected by WiFi, and if so is it on the main LAN or the Guest Network?
Double check the NAS for a firewall and if that firewall was configured to limit access.
Did you configure the NAS to reside in the router's DMZ zone?

Hi, thanks for your help.

The only thing that's changed is the router. I haven't changed the subnet of either FireTV stick or NAS.

As far as the router is concerned, everything is over ethernet - I have a set of Deco S7 giving me a mesh wifi setup, and the primary is connected by ethernet to the router. Every other device that operates on the Deco network is still working fine, as is every wired device. The FireTV stick is fine for things like Amazon Prime, Netflix etc.

One other thing I should have mentioned before. My TrueNAS also runs a MiniDLNA server in another jail. This server is being seen without any problems by devices on my network.

I haven't checked the NAS for a firewall - it worked before and I haven't changed the config. The only thing that's new is the router.

The router is pretty much out of the box. I've looked online about how to configure it to support a NAS Plex server, and the only things I can find go on about port forwarding, which I've tried with no luck.

I added the IP address of the jail to the DMZ, but that hasn't made a difference.

And now, having undone that DMZ change, I can't even connect to the jail in my browser anymore!

The old router and new router may have had different settings including different IP subnet range.
A suggestion. Rather than mess around with various settings like port forwarding, just do a hard factory reset on the router followed by a basic manual configuration to get the router connected to WAN and basic WiFi configured. Then, after the router is configured and operating correctly, reboot all devices connected to that router and recheck if the devices work as you want them to.

I only asked about the DMZ zone due to some people put their NAS into the DMZ zone for their own reasons. Putting a NAS into the DMZ zone is generally not needed unless one wants their NAS outside their router's firewall for their own use case.
