Permissions problem


I have gpredict running on Mac, Ubuntu 19.04 and Debian 9.
I have also installed it on my web server which is Running armbian ( Debian 8) on a Banana Pi M1.
I want to be able to auto start gpredict on boot up , but on the Arnhf amd64 version I seem to be able to start the data flow only if I start it with sudo. If I start as user the window comes up but without data.
Seems to me I need permissions set to access the network which connects to the internet.
Can anyone help ?
