Birds Eye, Base Camp COMMUNICATION FAILURE

MacOS Big Sur v.11.2.3

Base Camp Version 4.8.11 (4.8.11)

Garmin Montana 700 software v7.1

Just got this unit and CANNOT connect to Birds Eye servers, got it to work once (a week ago) but now it returns COMMUNICATION FAILURE every time I try to connect.

How do I fix this without loosing my already downloaded imagery?
