Hi Guys,
its been like this for few days now, whenever i try to access plex from my main PC
“Plex is not reachable.
Make sure your server has an internet connection and any firewalls or other programs are set to allow access.”
I have looked at the web for couple of solutions but no luck
Any suggestions please
[SOLVED]
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

Thanks for the tip msaithan, but would just running an uninstaller do and then reinstalling do the same thing?
