Open Port for Port Forwarding isnt appearing

I recently opened a port for a Minecraft server and was operating normally until today. When I attempt to view the active port it shows up as blank on my mobile app. When I attempt to reopen the port it shows my PC as not an option for a device. If I select another device it shows that the port is already open under my PC. I am unable to view or edit my active port nor am I able to recreate one.
