Remote Access Disconnecting after 4 seconds

Server Version#: 1.15.4.919
Player Version#: 3.83.1

April 20th - Hello,

I am trying to enable remote access on my Plex Server. After enabling remote access it says it is connected out side my network for approximately 4 seconds and then says that my Server is only visable inside my home network. Funny thing is that none of my devices can see the server either. I have a clean install of the Plex Server. I have verified that my port forwarding is active. I need help. Thank you!

I am having the same issues after latest update Version 1.15.3.876

Remote Access was never a problem prior to that

Please fix this

Same issue with latest PMS 4.993

Disabled Firewall and still same issue. Windows is updated too

Tried various configurations on my router and different ports

I’ve had this issue off and on over the last year or so. It has a different cause every time. Has happened when I haven’t changed anything nor even rebooted the server, and also after a reboot, or after an update of peerblock, or after a windows update, or after sneezing close to the server… This time, I once again changed nothing and did not reboot. It was recently updated to Windows 10 but had been working perfectly (faster than in win7 too) since. No windows updates auto-installed since 4/11, issue started 4/23. Have bypassed my router (plugged straight into MODEM), disabled all firewall in windows, disabled all windows defender features, uninstalled peerblock, tried other ports manually… At my whit’s end.
Gonna do a quick install on another box with Ubuntu and if remote works, will flatten OS drive on Plex and migrate it to Ubuntu. If it’s the same, I have to wonder if my ISP is blocking, except I have tried other ports…

Yep, me too. It says “fully accessible” for a few seconds, then says “not accessible”.

I have tried every permutation I can think of. I have followed the “definitive guide” and added Windows Firewall rules for virtually every port involved. I’ve turned on and off various port forwarding options in my router, on my VPN, etc. The computer NEVER goes to sleep, so that’s not it.

The best I can get is this on for a few seconds, off again behavior. And it works for some use cases (apparently via the Web interface, sometimes via TiVo, never via Roku). Is there a definitive guide to diagnosing the problem?

I’d love a detailed response from the Developers on How Plex decides if you have Remote Access. For the last year, Plex has said that I do not have Remote Access.

I upgraded the firmware on my Router and for now it works again, though I have no idea why it works now and did not for the last year.

So what is being looked for to make Remote Access work, a detailed response to this from the Plex Developers would be very much appreciated?

Yeah, it’s probably only working on devices that support indirect (relay) connections.

Still not working after firmware upgrade on Router

I’ve just created a new thread, but I’m experiencing the exact same issues. Nothing wrong with any of my networking equipment as I rebuilt a server to replace an old one, but didn’t change any of the rules etc. and it was working fine before. New server has simply replaced the IP address of the old one.

Well, I’ve just enabled all of the ports listed in this support guide.

Still no change in behavior. Says “OK” for a few seconds… then not.

It’s not anything you’ve done. There are hundreds of people affected by this issue at the moment and Plex have gone radio silent on us.

This could be the straw that broke the camels back for me. Will be investigating Emby in more detail.

Yes there are other forum threads but the issues vary and each long forum topic has many different causes for drop out of remote access.

Each case needs to be investigated to try and understand the cause and if there is a common theme

So please ensure debug logging is enabled on the server
See
https://support.plex.tv/articles/201643703-reporting-issues-with-plex-media-server/

Restart the server to make sure fresh log files are created

Then when the issue arises, please take screenshot of server remote access settings screen with show advanced and note down the time and collect the server logs
See
https://support.plex.tv/articles/200250417-plex-media-server-log-files/
and if using a manually specified port, to provide router settings screenshots of the DHCP Settings (Reservation) and Port forward rule

Thanks

Uploaded verbose logs and screenshot of my default port forwarding 32400. Nothing under Port Triggering.

On my router, it says my IP address is 100.80.x.xxx, but whatismyip shows 175.142.xx.xx. Is this a problem ? I called my ISP, and they said we are using a Dynamic Public IP.

I tried NoIP DDNS, and still does not help

OK, here you go. Logs & screen shots in the zip.

Pie-on-face moment for me.

I fixed my issue. My old server had two NICs with two IPs. One for management traffic, the other for Plex traffic. I put my management traffic IP into the new server, but the forwarding rules were set up for the old one. I saw this and just assumed it was the same issue without tracing traffic properly.

Best,

Yes

This is CGNAT giving Double NAT

See the section on CGNAT on this support article
https://support.plex.tv/articles/200931138-troubleshooting-remote-access/

Basically we need to make sure there is no Double NAT and you would need to see if your ISP can offer you a dedicated IP address at a reasonable price

The connections to the 175.142.xxx.xxx to port 32400 are not getting through - suspect because of the double NAT

thanks for the info. That just shows that remote access problems can be due to many reasons

Thank you - The connectivity tests to your public IP and port 20069 are not getting through

What security software do you have running?
Is the network interface in windows showing as Private Network ? Sometimes windows switches to unidentified or public after windows updates

could you add a port rule in the firewall
Protocol: tcp
local port = 32400
remote port = any
remote ip = any
Action = allow

May be a double NAT issue?
Is the wan ip on the router the same as the 107.181.xx.xx IP and being the one you get from canyouseeme.org ?

I tried the IP and port 20069 and I could not reach your server

Yeah I tried UPNP as well

Emby was able to pickup the server on my UPNP list, but Plex does not. Router on the latest firmware too.

Disabled Windows Firewall too. PMS is on the Allowed List. DMZ is enabled on my router for my local IP
