The username and password fields aren't being carried into the modules/plex.py file through cherrypy to htpc.settings, so when the ping method gets called it never triggers the initial plex signin to get an auth token for all other requests.

I was able to rig a 'solution' for this (which I do not recommend anyone to use, unless you know what you're doing) that involves putting an auth token ripped out of a plex web player XHR's query parameters.

Then you shoehorn it into the application logic as a hard-coded value.

The hack can be condensed to: sed -i "897s/.*/ authtoken='YOUR_TOKEN'/" modules/plex.py (12 spaces before authtoken, despite my inability to properly format) [edit: until the token expires, at which point you can grab a new one and rerun this]

This issue comes of from time to time but i cant seem to reproduce it. Ill take alook and see if cant make this more robust.

can you try to signin manually using http://ip_to_htpc_manager:port/plex/myPlexSignin?username=your_username&passord=your_passwird

Sorry for the delayed response, and thank you for your help on this. I just reinstalled HTPC Manager and it is working fine now for some reason. Thank you for the help.

In my case, with near certainty this was because I had the manager setup to point to Plex by local subnet IP instead of by loopback address. The local subnet was exposed via a reverse proxy with basic auth enabled (which was cached for the browser, making it not obvious).

Changing the IP should fix it, but I haven't verified.

(Edit: I confirmed this was the case)

I have the same issue and don’t understand the fixes

I have just started using this and have the same problem, is there a fix coming for this?

[morpheus2n2]

Found the fix, I set up the rest of HTPC and then obviously restarted this seemed to then allow plex to work just fine :)
