Can't connect to Sonarr from another machine

So both remotely and on my local network I can’t access Sonarr but when I try SAB/CP/Plex etc they all work fine. I’ve amended the port restarted the machine and server played around with the ports on the router. This has only recently happened does anyone have any ideas ?

Check the Windows Firewall and make sure it has an opening for the correct port AND the correct profile (home/public/domain).

Ah great thanks not sure what happened there…
