Luba 2 powering off, can't complete a job

Hello,
I bought my Luba 2 about two weeks ago, and I’m feeling a bit frustrated with some errors I keep encountering. The truth is that I’ve only managed to complete a full mowing session once, with issues occurring every other time I’ve tried.

The main problem I’m experiencing now is that the robot starts working and, after a few minutes, it stops with the message: “Working paused due to power off. Click play to continue”.

If I click continue, it resumes, but within 5–10 seconds, it stops again, often making a sound like a knife cutting. To restart it, it says:
“For accurate positioning, please ensure that the robot and the RTK reference station are not obstructed by any objects” . I manually drive it for a few seconds and then it allows me to start again, only to stop shortly after

I’ve tried moving the antenna several times and finally placed it on my house roof, where I’m absolutely certain there are no obstructions whatsoever.

I’ve also done a factory reset, moved the base, and remapped everything, but I’m running out of ideas. The error messages aren’t clear.

I read in another post that this could be related to heat and direct sunlight on the robot. I’m in a warm area where it’s currently summer.

Any ideas?
