Remote Access To Plex Server Keeps Disconnecting

[kerlimann_gmail.com]

Server Version#: 1.32.1.6999
Player Version#: 4.106.1

I used to be able to successfully access my Plex server remotely, but after not having used remote access in almost 3 years, I noticed it is no longer working. When I try it now, it briefly shows that it’s fully accessible and after about 5 seconds it changes to “not available outside your network”. My router (AT&T Pace 5268AC) is configured to forward from a static IP address to port 32400 using instructions I found a few years ago (i.e. created PLEX UDP and PLEX TCP applications under the static IP address) and it all used to work fine. Remote access without manually specifying a port has never worked (and still isn’t). I have not made any firewall changes since the time it worked, but perhaps my ISP (AT&T) has made changes, or Plex Server updates over the last years are causing this issue. I have also tried remote access while disabling the firewall of my security software (Norton 360) to eliminate that as a potential culprit. I am not very savvy when it comes to IT/networking troubleshooting, so I’m hoping someone can provide guidance “for dummies” and step me through the process on how to identify and fix the issue. TYIA!

If your setup and network are still the same, it’s likely some change on the ISP side.
Does your router still get a publicly routable IPv4 address from your ISP and can you see the public port from your port forward from outside your home network (e.g. using a service like canyouseeme.org)?

As for your router config – there’s no need to forward UDP traffic… just TCP.

The Basics of Remote Access Troubleshooting

When it comes to remote access, there’s a lot of different factors which can impact your setup. Some are under your own control, others not so much. First off… there’s a dedicated support article on troubleshooting your remote access. I strongly recommend you have a look at that. Find below some additional remarks on how to troubleshoot your remote access setup. Review your internet access / remote access configuration It’s good practice to review if Plex gets the correct public IP address…

Could you please explain how to check a) if my router still gets a publicly routable IPv4 address from my ISP and b) if I can see the public port from my port forward from outside your home network?
