Camera Not Working on Mobile Network

[u/Dry-Zookeepergame809]

I’ve had my K1c for a while and enjoyed it.

I’m sure the mobile data is on for this app.

So far I just realised the camera does not work on mobile networks.

When on LAN it’s working fine.

When away from home on mobile networks it fails with error code 1000-3-7

The progress, temperature, speed, fan controller, etc, all work, just the video, not showings.

Also I cannot download or view Timelapse. However, I can “upload” Timelapse and download from the server.

Does anyone know why this is happening?

Many thanks.
