Cannot connect to my Cerbo GX using the VictronConnect app pn my andriod phone

The Cerbo GX (MK2) i mounted in my boat. When the Serbo GX pops up in the VictronConnect app on my Android phone, I key in the 6 digit PIB code. The progress bar goes to 95 and starts all over again two times before I get an error message. I’ve tried to disconnect the bluetooth connection to the Serbo GX on my phone, restart the phone, disconnect the 12V power and restart the Cerbo GX, but nothing works. I’ve also tried using an Andriod tablet, but that doesn’t work either.

What can/should I do?
