Other devices can't connect to my Plex

Server Version#:
Player Version#:

Hi.
I have had plex for a while now, but at the moment it is not working on any other devices. They are both on the same internet, and plex work perfectly fine on the main server. I tried to connect both on my smart TV and the playstation, none worked. Tried logging out of plex on both places and log in afterwords, did not work. Could you help and give me some tips how to fix this?

Will need some more info.

Server version:

TV brand and model:

But at a guess you need to add your Server LAN IP address in Manual server settings of the Plex TV app.
