Cannot load M3U8: crossdomain access denied

mediaplex

I am getting the error message "Cannot load M3U8: crossdomain access denied" when trying to access my Plex server through the web interface. How do I stop this happening?

This typically happens if you are behind a corperate or school firewall. This is a browser setting that needs changing.

IE: Go to "Internet Options" > "Secuirty" > "Internet" > choose "Custom Level" and scroll down to "Miscellaneous". One of the options should be "Access data sources across domain" - set this to "Enable".

Ubuntu – 401 error when accessing Plex Media Server

My problem stemmed from the fact that I was hitting my.aws.pub.ip:32400

The correct URL to hit is my.aws.pub.ip:32400/web/index.html or my.aws.pub.ip:32400/web, unless you have setup some sort of reverse proxy to tell AWS to send all requests on that port to PMS.

Here is what I originally missed in the PMS documentation.

If you installed the Server on a device like a NAS, or the Server PC is somewhere else in the house, you'll need to know the Server's internal IP Address. Once you know that IP address, on a PC in your home:

Open a browser window

Type http://server.local.ip.address:32400/web into the address bar (e.g "http://192.168.1.5:32400/web")

The browser will connect to the Server and load Plex Web App

In cases where you're installing Plex Media Server on a remote system, you'll need to first connect to it so that you can access it as if the system were local. Please see information in the Installation article for details.

Plex over double NAT

I already had an empty bind address, the problem was I needed to specify to bind to all addresses, like this:

ssh -nNTv -R 0.0.0.0:32400:localhost:32400 root@<public IP of remote host>
