Plex on a Qnap. 1 is default other in docker

Plex Media Server
1

I have plex on my qnap (1.40.3.8555) that will not connect directly and the remote connection starts green then a few seconds later goes red .,
My member can stream and their Ip is shown as 127.0.0.1.
Now on the same NAS I have another Plex in Docker. (1.40.2.8395) This connects as it should with remote being green and member shows their actual IP.

I have used Plex for over 10 years and have tried a multitude of port/ips/settings but remote will not stay green.,
BTW while it is red it is streaming but via relay.

Same box - one docker plex connects (green) and default (red) does not !
I have now run this on another qnap NAS and same result. Docker works and NAS uses relay .
Any new suggestions ??

1st: keep in mind that “the remote connection starts green then a few seconds later goes red” means that your remote access setup is not working to begin with. Plex keeps listing the remote access status as “green” while it’s testing the setup – this can take a few seconds, up to 1-2 minutes in extreme cases.

You might want to review the QNAP’s network settings – e.g. if there’s a bad DNS preference or DNS rebind protection to mess with your (default) server to fail communicating with Plex’ backend. The docker container could be configured with a separate network configuration and therefor not be impacted by such restrictions/errors.

Thanks .
I have changed dozens of things in my NAS setup but will look again.
A bad DNS preference ? Where would that be ?

4

Could be a DNS server that fails to resolve plex.tv or plex.direct, therefore „blocking“ that communication.

I use 8.8.8.8 and 8.8.4.4 as my default. I have changed to the DNS address my ISP supplied but no change.

You might take a look at the server logs (Plex Media Server.log) with debug mode enabled… this might show an error message or warning why/how the server is failing to connect.

Thanks for your help.
There is 144 logs This the first (i think) .
This one i found odd .
com.plexapp.system.log (40.5 KB)

2024-06-14 22:34:39,891 (7fa71ed75b38) : ERROR (networking:197) - Error opening URL ‘http://127.0.0.1:32400/servers’

Look for the file that’s called „Plex Media Server.log“

Today all is working . I have changed so many Things I have no idea what actually fixed it.
I had also ran port checker and the port in docker is open . The port on my nas showed closed .
Today Both are now open !
I had also contacted my ISP about the port issue and i was told they were checking .
thanks for your help .
