New Router today Plex Server Wont Open

[monkeyboy72]

Hi today I received a new 5g TP Link router, everything set as normal except cannot get Plex server running again?.
Ive even uninstalled and reinstalled twice, tried shutting everything down, cleared browser cache but each time the PMS just will not appear.
My NAS is F2-221 TOS 5.34
Spent hours on this and read loads of previos posts but nothing working, is driving me nuts. Can anyone assist please.

Finally managed to get it working, uninstalled again but this time went everywhere I could see the word Plex mentioned in the folder tree and deleted everything I could find, then reinstalled but directly from Plex website and thank god its back working again.
