Remote Access Down Since Update (Version 1.11.1.4730)

Has anyone else had this update kill their remote access? Local play still works. I have tried logging out and in of the account, restarting the server, etc. Running media server on Windows 10 Pro (newest update) with Ethernet connection to router.

Media server running on Win10 x64 1709 enterprise, updated to 4730 yesterday, no issues with remote access here.

Have you enabled Port Forwarding in your router? If not, I highly suggest doing so. It will remove 97% of remote access issues.

Fine for me as well.

Check your network connection in windiws to make sure it says private network and not unknown network

If that status is correct then try to disable remote access in server settings. Wait 30 seconds and then enable remote access. Make sure you do not repeatedly click retry and if you are using automatic port allocation, you should find it is more reliable with a port forward in the router and ticking manually specify port and entering the public port that you forwarded to the server local ip which of course must be a dhcp reservation or static ip outside dhcp range

I appreciate everyone’s response. The network is set as private in windows. I just tried disabling remote access within Plex for 5 minutes and then enabling remote access to no success.

On my router I have static IP set up for the server with port forwarding and uPNP enabled.



Looks good - suggest going through the checklist on the troubleshooting article https://support.plex.tv/articles/200931138-troubleshooting-remote-access/ checking out double nat, cgnat, mtu size
Also check that you are not blocking any European ip addresses that are coming from plex to check out Remote Access

If problem remains ensure debug logging enable,pd, restart server, retry the disable, wait, enable and capture screens and logs

I have done the above steps and still no outside connections. Per before, which I forgot to include, whenever I pull up plex on iOS (which has been updated to the newest version), it does show it’s working, but only as an indirect connection.

All looks good apart from the fact that tcp port 32400 is not reachable from the outside

The indirect route is the back up plex relay route that is available when remote access through your normal route does not work. It uses https port 443.

So please check that the public wan ip addrsss on your router wan status page is the 74.132.xx.xx - if it is not, then there is a double nat

If it is this IP address, then next area to look into is security software and firewall on the pc

What security software is in use ?

Can you look into creating a firewall port rule
Inbound port rule
Local port : 32400
Remote port: any
Remote ip: any
Remote network: any
Programs: any

Router’s WAN reads 74.132.xx.xx (aka no double NAT). I use window’s built in firewall and security software. I verified the plex app has permission through the firewall, but also added the new port rule per your suggestion. Still no direct connection. I am running a windows insider version of windows pro, but Plex has been running great on it since the new plex update. My motherboard is a Gigabyte Gaming 7 (version 1.0) with killer networking, but like windows, running all the newest versions and updates and plex was running fine with remote access.

You could use wireshark to check if we are reaching the pc on 32400

So suggest using a phone on cellular and with Wi-fi disabled trying browser with http://74.132.xx.xx:32400/web and finding your wan IP address on the phone and then looking at the wireshark capture to see if the request came to the PC

This would help in directing the investigation

I set up wireshark and navigated to http://74.132.xx.xx:32400/web on my phone on cellular. The webpage loads correctly with the green lock in the plex page, showing direct connection. On wireshark it looks like the requests are coming in, but the IP address is different than if I try to find out my ip address of my phone using whats my ip.

For some reason, after closing out of wireshark, Plex is now showing successful remote access. I am unsure what fixed the issue, as I had not changed any settings.

Good news - but a mystery

Did you reboot anything in the meantime ?

Yes. I just rebooted the server to verify it was still holding its remote access.

I was thinking earlier may be a reboot fixed the issue or firewall restart or router restart - but if the reboot was done after it started working then remains a mystery

Thank you for your help. If it arises again, I’m sure I’ll be back!
