Can't login on Samsung TV PLEX app - "frozen" login window

[capoeira-pl]

Server Version#: 1.18.4.2171
Player Version#:

I’ve been using PLEX app at my UE55D7000 Samsung TV for years.

Recently PLEX wouldn’t connect (blank black screen) so I deleted and reinstalled the PLEX app (version 1.01900) updated 10.11.2016

Then when I entered the TV PLEX app it asks to login my Plex account, but the login window is „frozen”.

I can’t move between fields to type in the login data

It looks like it (screenshot)

When I try to connect with the Server, it says turn „Require authentication on local servers” off in Media Manager.

I can’t see this function in Media Manager. Probably it is already outdated.
What should I do?

I can’t see this function in Media Manager.

in the web app app.plex.tv
Settings - Server - Network - ‘Show Advanced’ - “List of IP addresses and networks that are allowed without auth”

You might wanna configure your router, it hands out always the same IP to the TV.
(usually called “DHCP reservation”)
