i want to have access in mal local LAN to my plex server without auth. I have specified the my local lan under “List of IP addresses and networks that are allowed without auth” and this works fine if I access the server via IP in the browser. If i set a local DNS record in my router to avoid using the IP I always get the message “This application is at [DNS name] and is not hosted by Plex. Continue only if you recognize this server and wish to grant access.” and I cannot access the server without auth. What am I doing wrong?
When you setup the server to allow your lan without authentication, it will not prompt for any.
The “Not hosted by” is plex/web telling you it’s not Plex’s server (because it’s your server). You’re seeing an attempt to authenticate. (app.plex.tv ??)
You can only use IP addresses / DNS names which you create and manage including any remote access by yourself. The server is in full manual operation mode.
