So I've installed another browser fresh and I've not had any luck. I do have this to say though:
Just before I got the white screen, I attempted to go into plex settings and enable remote access. This didn't work and from then on, I couldn't get back in.
I logged in via plex.tv and noticed that the connection to my local server had something which said 'indirect access'. Something like a yellow triangle.
I've uninstalled and reinstalled a few times, including trying other plex dockers and they all do the same thing.
I've been clearing my appdata folder each time i did a reinstall.
It has done this once before when I was initially installing plex. It basically solved itself randomly one day without me doing anything.
From what I was doing just before it died, I'm convinced it has something to do with trying to enable remote access in plex, I just don't understand why the problem is persistent even when i remove the container and its appdata folder.
Any ideas?
Thanks for helping.
