On my PC when i click on the PLEX app i get Plex is not reachable. But I can use the app on my phone and it works. Has anyone had this problem? It does have an internet connection and I disabled my firewall and still nothing. Any suggestions?
Thanks
Here is my solution maybe some will get benefit out of it
1- Close Plex from Task manager (exit plex completely)
2- Deleted System.bundle
location “C:\Users\xxxx\AppData\Local\Plex Media Server\Plug-ins”
(Replace xxx with your user or just navigate from C drive)
3- Deleted Framework.bundle
location “C:\Program Files (x86)\Plex\Plex Media Server\Resources\Plug-ins-9f65b88ae”
(you might only have Program files without 86, please make sure, but still its easy to find file)
4- Run the browser at http://localhost:32400/web/index.html and Wait for around 5-10 minutes maybe.
(you will see the page turn white then light blue, random things)
5- Re-install Plex from https://www.plex.tv/downloads/
6- Delete WebClient.bundle
location “C:\Program Files (x86)\Plex\Plex Media Server\Resources\Plug-ins-9f65b88ae”
(because If you dont delete you might get error “Server settings are unavailable” if you go to setting)
6- Wait for another 5-10 minutes
7- Run Plex again and login
Hope this will help some of you
