I ran into the problem where I install Plex on my Synology NAS and the try to open it, only to be greeted with a page time out error. I looked on this forum only to find people in the same boat but without a solution:
The answer is that you need to authorize the 32400 port on your NAS. I’m not sure why it works immediately for most people, I only assume I locked down my NAS more securely than others, or the automatic enablement didn’t occur. Anyway:
- Log into your NAS (with admin rights)
- Go to the NAS Control Panel
- Click on the Security Option
- In the ribbon, select Firewall
- Click on the ‘Edit Rules’ button
- A new ‘Create Firewall Rules’ window opens and click on the ‘Create’ button
- Choose ‘Custom’ radio button under Ports. Leave the Source IP to All and the Action to Allow
- Click on the ‘Custom’ button in the Ports ‘section’ of this window
- A new window opens, and choose Type: Destination Port, Protocol: All, Ports: 32400. And then hit the OK button.
- Hit the OK button for the ‘Create Firewall Rules’ window
- Hit OK for the ‘Edit Profile’ Window
- Hit Apply in the Firewall window
That worked for me. Good luck.
