Hi,
I have been using ThingSpeak upload on several CO2 detectors based on ESP32 Arduino board, for six mounth.
Some are using direct API HTTPS requests to write values on ThingSpeak channels. Those are still working (through a proxy)
Others with similar programmetion but using ThingSpeak secure Communication Library for Arduino, have stopped uploading values since 19/07/2022 around 16h.
Was there any non publiched modification on the library at this time ?
Did any body notice something similar ?
I have not investigateg the error yet...
Thanks for feed back,
TC
