FS Radio Panel Connection issue

Hi Guys

I am using FSX and chose to use the App from Tambucho, FS Radio Panel Pro. This was running perfectly and I was running 2 tablets and two old mobile phones all with different screens to aid my experience.

These were working well and operate using a local network. The other week the PC changed its IP address and i changed it in the settings on all the devices and all was well. Last week the IP address changed again and now despite entering the new IP address nothing connects.

I have reloaded the server software (FS Panel Server) and reloaded the apps from the play store but still no connection.

This is doing my head in.

Any thoughts please.
