That is by design. Please understand that we provide hosting for websites, i.e. things that produce pages that are viewed in web browsers. To help enforce this, we have this security system:

Our hosting is not intended for IoT data collection services, and you’ll have a very hard time if you try to use our hosting for it.

Personally, I would go with a small, cheap, low power home server, like a Raspberry Pi, to handle the data collection. If only for the privacy benefit of the data not leaving my own network.
