There many posts regarding this issue but none more recent than 2023, and none that have helped me to resolve this issue.
In short, I took a working Plex install on an old, unsupported CentOS machine and built a new Ubuntu box thinking I could simply copy/paste the old settings into the new following several tutorials. Well, that didn’t happen.
No big deal, I simply started from scratch and rebuilt the new server. BUT, while the old one permitted access without auth, the new one doesn’t. I opened the old one and screen captured the network settings, copying everything into the new one. Nothing I’ve tried has worked.
When I open my local Plex server URL, it attempts to open the local server, but then redirects to “https://app.plex.tv/auth/#!?clientID=…” requiring me to sign in as if its a remote machine. And, when signed in playing a locally hosted video, it shows my web browser use as a remote client under the Bandwidth graph in the dashboard.
I have tried all of the following in the Network-> List of IP addresses and networks that are allowed without auth:
192.168.10.0/255.255.255.0,192.168.20.0/255.255.255.0
192.168.10.0/24,192.168.20.0/24
192.168.10.50/255.255.255.255,192.168.20.60/255.255.255.255
192.168.10.50/32,192.168.20.60/32
I’m at a loss on how to resolve this. Any help/suggestions would be greatly appreciated!
