Can not query API from IoT Device

Hi

I am using an Azure Function App for an IoT device (microcontroller + GSM module) to query an API.

Since around 4 AM UK time today, the API has not been accessible from the device, even though it works fine when accessed via a web browser. This suggests the issue is likely related to TLS/SSL or cipher suites, possibly something failing during the handshake. It had been working fine until now.

I am currently running version **4.637.1.23604**. Is there any way to roll back to a previous version, possibly one that was active about a week ago? As my device without the API connection can not be controlled.
