Paradigm Touchscreen Remote iPadOS version; iPad OS version 17.1.1 on 3rd generation iPad Pro

My remote stopped working.  It had been working since Paradigm software and touchscreens were upgraded in February 2022.  I suspect that settings were cleared or something else happened during an app update.

The web interface on the iPad to Paradigm is working so I know wireless network connection is good.  P-APC is, Touchscreen 1 is  Touchscreen 2 is a portable without IP address.

Checking Touchscreen 1, the Mobile App Settings are:  Mobile App Connection is On, Passcode is blank, Port is 49044

I've configured the iOS app with IP address and get the message:  Error connecting to P-TS7  Check IP or network settings.
