Plex Remote Access being.... odd

Server Version#: 1.25.3.5409
Player (Web) Version#: 4.73.3

Alright, so I feel like I’ve exhausted every troubleshooting step. So this is my last place to turn. I’m getting the infamous Green Check for remote access for about 10 seconds and then reverts to Not available outside of your network.

For starters:

Firewalls are turned off.
Ports are manually port forwarded through router (32400 internal, 40000 external)
Computer is given static IP through DHCP on the router

I still can’t get the port to be seen by canyouseeme.org, nor any of my other ports for deluge, sonarr, radarr, etc.

I’ve tried to access from both Plex Android app as well as the web app and neither seem to be working atm.

I will upload logs as soon as I get a hold of them.

The other details of my network are just cable modem going into one router with one wireless AP, and one switch. Plex server is plugged directly into the router.

Here are the attached logs. Hopefully these can provide some insight.

It looks like you are in a double NAT situation (router behind a router).

The router is telling the Plex server that the router’s public IP address is 192.168.0.31, which is a private, non-routable IP address, not a public IP address.

Any chance the cable modem is actually a router?

Jan 24, 2022 20:54:29.252 [10812] DEBUG - PublicAddressManager: got WAN IP 192.168.0.31 from router
Jan 24, 2022 20:54:29.252 [10812] WARN - PublicAddressManager: WAN IP is a private IP address

One way to check:

  1. Power off the cable modem and your router.
  2. Disconnect any Ethernet cables from the modem.
  3. Power on the cable modem and wait until it syncs with the network.
  4. Connect a computer to the cable modem via Ethernet cable.
  5. Check the IP address assigned to the computer (Windows 10: Settings → Network → Properties).
  6. If it is a 192.168.x.x or other RFC-1918 address then the cable modem is really a router.

Yes, thats possible, didn’t really think of it, just thought that the network its giving out is a neighbours… Will give it a try tomorrow. Thanks

If it is really a router, you’ve a couple of options:

  1. Contact your ISP, ask them to disable the routing and make it work as a true cable modem.
    Your router will then have a public IP address, handle DHCP on your network, port forwarding, etc.

  2. Leave the ISP router functioning as a router and change your router to function as an AP. You’ll have to login to the ISP router to add port forwarding statements, DHCP reservations, etc.

So change it to bridge mode? and then port forward everything from this “router” to the other one

Edit: Changed to Bridge mode, and remote access seems to be working…

however speeds are much reduced than before, IP’s given from the modem are 192.168.0.x and the router is 192.168.1.x.

If the ISP device is in bridge/modem mode, it should give you a public IP address.

For example, my cable router is in bridge mode, and supplies 76.185.x.y. My Asus router then deals with port forwarding, DHCP, etc.

So just to clarify the modem spits out a public IP and then do I have to do anything with the WAN IP Address on the router side? I already have the port forwarding/DHCP set up on the router. However, just getting reduced internet speeds on all devices is now the problem.

Not unless your provider requires a login for some reason. Most do not.

Here’s my setup:
Spectrum Cable Modem <–Ethernet–>Asus Router<–Ethernet–>Switch<–Ethernet–>Plex Server

Cable modem supplies a public IP, 76.185.x.y, to the Asus Router. The address is visible on the Asus Router’s home page when I login to the router. It is also the address that appears when I go to whatismyipaddress.com or similar sites.

Asus router supplies 192.168.1.x addresses to my local devices. Plex Server and two PCs connected via Ethernet. Phones, tablets, etc connected via WiFi.

Port forwarding statement for Plex is in the Asus router.

Switching one router to bridge mode should not affect speeds.

Connect a PC directly to the modem, bypassing your router, and check the speed.

Ok this is very similar to my setup as well. I have another desktop wired on the network and the speeds are normal. I don’t have a VPN running either as well. I have the IP Manually Assigned on the router as well, I doubt that would be doing anything irregular though.

Found the issue, it seems the connection is running at 100Mbps on the controller. Not exactly sure why it changed, as the speeds were normal before changing to bridge
