Describe the bug
Since the latest Dishy update earlier this morning to 9f4d05a4-65b6-411b-ba6b-8dd91c64e02c.uterm.release the exporter is unable to collect data via gRPC.
Running in a standard Starlink setup without further parameters it successfully gets the dish ID

time="2021-06-24T22:15:59+02:00" level=info msg="dish id: ut01000000-00000000-00013135" source="main.go:28"

However, each time /metrics of the exporter is queried, it returns the following:

# HELP starlink_dish_up Was the last query of Starlink dish successful.
# TYPE starlink_dish_up gauge
starlink_dish_up 0

The console/log shows the following error:

time="2021-06-24T22:15:59+02:00" level=error msg="failed to collect context from dish: rpc error: code = PermissionDenied desc = " source="exporter.go:290"

It worked fine with the previous release a4908729-5051-4d3b-aacc-446ef9b26cdc.uterm.release.
Data is still available fine when accessing the web UI normally.
I didn't have time yet to look further into it, so sorry for the somewhat unqualified bug ticket.

To Reproduce
Steps to reproduce the behavior:

1. Get a Dishy with the mentioned software version
