Stop a VPN-protected Plex Server from deciding for itself whether direct access is possible

Plex Media Server Remote Access
1

I am running the latest server version (QNAP) and using the latest Android client.

The server is behind a VPN. In order to access it remotely, I obtain a VPN connection, tunneling all ports on the client device. I can then connect to the linux NAS running Plex Server, and every other computer on my VPN-protected LAN with no issues. However, the Plex Server instance seems to be constantly testing whether some arbitrary WAN client device can connect to Plex Server, which always fails, because the WAN address that Plex uses to run this test cannot be configured with my VPN creds (nor would I ever want to do this). Thus, Plex Server throttles all my streaming even when incoming direct connections are possible from a VPN-connected client device. Is there a way to disable this behavior? In essence all I need is for Plex Server to accept all incoming direct connections and not try to decide for itself whether this is possible and automatically downgrade performance.

Server Version#: 1.16.6
Player Version#: 7.26.0.14578

Try using cellular data and see if video quality performance increases. If it does its your ISP most likely.

@BigSlimVdub thanks for the tip. I’m wondering if this has something to do with the fact that my server is on university residential network, which is behind the university VPN. Is it possible that this VPN is blocking incoming requests from Plex clients?

More so the university IT department is blocking incoming or outgoing port 32400.

Setup using a different port and it may work :slight_smile:

or they may be limiting bandwidth, who knows but if you try connecting via cellular it will prove out its ISP/IT related issues.
