Chateau on 7.1rc3 - LTE scan does not show results

Hi!

I have a problem on all of my Chateaus:

If I try to scan for the available lte networks, I do not get any results.

/interface/lte/scan 0 duration=60

→ No results, although the interface is connected.

Do you have any idea on how to get the available networks?

Thank you and best wishes
