RUTM54 Realtime View of Mobile Signal not working

The Realtime Data View of the Mobile Signal is not working on my RUTM54 since a few months (and firmwares).
Tried different Browsers and PCs, but no data is shown. All other Realtime Views are working.
In Network - Mobile i see that 4 Bands are connected.
In the Browser Diagnostics i see that status json is polled all few seconds and seems to have the signal information inside.
Firmware RUTM_R_00.07.23.7

Maybe someone has a solution for me?

Greetings,

Apologies for the delayed response.

Could you please send a screenshot of how the Status → Realtime Data → Mobile Signal screen looks for you?

Is only the graph empty or are you not able to see the signal strengths on the bottom of the screen either?

Have you tried using an incognito/private window?

Best Regards,
Justinas

Hi,

thanks for your reply!
Its completely empty. I tried Edge and Firefox, both normal and incognito.

On Status → Network → Mobile i see 3 connected Bands.
I have several M51 running with functional Realtime View.
