EHS5T SSL/TLS TCP connection problems with Microsoft Azure IOT Hub | Telit Cinterion IoT Developer Community

I have to connect a EHS5T (Java program) with Microsoft Azure IOT Hub using the MQTT Port 8883. I have already successfully connected my EHS5T to other MQTT Brokers with SSL and the IOT Hub is also working with other devices. After connection try timeout there is the message: "Remote peer has closed the connection". I have asked my distributor for support and got the firmware 3.001 ar 14 and the actual SDK. The modem has already firmware 3.001 ar 14, and a SDK update not helped. I have seen similar problems in the forum, that are solved by firmware update to revision 44 or higher.
Where can I get a newer firmware? My distri doesn't have something newer.
Does anyone has connected a EHSx with Microsoft Azure IOT Hub? Maybe I am doing something wrong. I have loaded the Microsoft Cert. (Baltimore CyperTrust Root 2025), enabled and disabled security. Nothing works!
Thank you for your help.
The A-REVISION 00.000.14 probably does not work with Azure. There were some updates of ssl libraries since that release and communication with Azure should be working with newer releases. Currently the latest available public release is A-REVISION 00.000.51. I'll send you so you could try.
