Hi, Has anyone successfully connected to azure with the HL78xx module via TCP/SSL? I connect with AWS fine but there seems to be a problem with azure and i’m guessing its root certificates that don’t quite work with the module. thanks ---

Hi hkiol, Which type of authentication are you using: server or mutual? Have you stored root CA to the module by command AT+KCERTSTORE=0 ? Thanks, ---

Hi @jerdung , I am using mutual authentication and have stored all the certificates correctly. I have successfully done the same procedure with no problems for AWS so I suspect my methodology is correct. I also configured all the cipher suites. Could it be that the module doesn’t support any suite from AZURE? I’ll double check again. The certifications I use for AZURE are correct as I connect OK with them from an MQTT client (MQTTfx). So all configurations from the AZURE side seem to be fine. I am just unable to connect with the module. thanks ---

You can get supported list or configure cipher suite at pages 169-171 in document below: [https://source.sierrawireless.com/resources/airprime/software/airprime\_hl78xx\_at\_commands\_interface\_guide/#sthash.M11xjPEW.dpbs](https://source.sierrawireless.com/resources/airprime/software/airprime_hl78xx_at_commands_interface_guide/#sthash.M11xjPEW.dpbs) Thanks, ---

Hi Don’t know if its been solved - If this is the case please let us know. I’m having troubles too with connection to MS Azure … Though having SSL/certificates working … I’m sending - through TCP - a pre formatted http GET msg … This gets rejected by server … My log of full comm here below … stripped for security reasons … /johnk[20210915\_NewHL7802\_Connection2Server.txt](https://forum.sierrawireless.com/uploads/short-url/smCO1R0VJsTOIwSGXdJhecaUyxY.txt) (4.8 KB) Date: 20210715/JohnK What: Logging of connection establishment towards MS Azure Company server Sending using TCP, a preformatted/handcoded http-GET Status: Failing on comm with server; Cause: Azure Server received http GET request on correct (443) port but apparently a http and not https command - hence missing encryption ???
