Plex not reachable locally after different router

General Discussions

Dear forum,

I am turning to you ppl in despair.

I recently moved country and brought my server with me.
Today, I have connected the server to the new router. It gets a local IP of 10.0.0.10.
When I browse to this IP, I get to sign in, the plex website loads, but it tells me that my server can’t be reached.
This is weird…this is my local network…how come the server can’t be reached?
Under settings, there is no “server” tab, just web, user and devices

What makes it even weirder is that the android app can locally connect to the server (I’m guessing it is not using the web interface, but relays?). and stream content

I brought my “old” router with me, plugged the plex server in it and the website loads fine locally .
However, I can’t use this router permanently, as it uses an ethernet port and my new place only provides a DSL cable.

So to summarize,
The server works fine, even the remote connection.
Therefore, I am probably looking at a faulty router setting and I would love to know what can cause this.
I have tried to deactivate the firewall, putting the server in the DMZ, just to see what may cause this problem

If anyone has a suggestion for me, please reply.

could be DNS Rebinding Protection in the router for the secure connections

You can try changing web settings (Settings / Web / General / Show Advanced and Allow Fallback to insecure connections enabled for local network

You can read about secure connections and DNS Rebinding here

Hi sa2000,

Thanks for the reply.
Google DNS was set.

Also, neither a secure nor an unsecured connection is possible locally.

Do you have any other suggestions?

You have comcast… you need to enable MyFi for that router it needs to reconfigure your network… from your ‘old’ settings, it’s a wizard takes like 2 minutes.

Can you ping the server where plex is installed? If you can then it’s not the router… it’s something else. Maybe you have a different IP and plex is setup to use that ‘old’ IP not the new one you need to restart plex server once connected on that NEW router… see if that helps…
