Plex,TV can't find server

Got home from work and started my media server up. Plex is running fine on it, Boot up my downstairs PC and try to connect to Plex and it can’t find my server. Check the server, all settings looks fine so I try again no luck.
All settings appear to be fine. I’m able to log in locally and check but can’t via any other TV

All settings on the server haven’t changed so not sure why it’s not working now

its the latest version update. it is the worst. hopefully they will either roll it back to the previous version for us or fix it asap!
