No more consumption readings on my 'Control' app or my web dashboard

Hello,
Since Wednesday, June 25 at 6 p.m., I no longer have any consumption readings from my Netatmo devices (power outlets, etc.).
My app and web dashboard no longer provide consumption readings. 
The API no longer returns consumption data after this date:

[{"beg_time":1750802400,"step_time":3600,"value":[[38],[38],[38],[38],[38],[38],[38],[38],[38],[38],[38],[38],[38],[38],[38],[38],[38],[38],[38]]}]

The devices are properly connected, they appear, they respond to commands, and the instantaneous consumption is correct.
However, the hourly/daily/monthly consumption readings do not appear anywhere.
Is there a problem with the servers?
Sincerely,
