IoT Modules LTE Standard Module

Hi,
I’m trying to connect to Azure iot hub using MQTT with CA cert and SSL enabled. Getting this err code +QMTSTAT: 0,1 “Connection is closed or reset by peer.”
After AT+QMTOPEN =
AT+QMTOPEN=0,“test.azure-devices.net”,8883

OK

+QMTOPEN: 0,0

AT+QMTCONN=0,“clientid”,“test.azure-devices.net/test/?api-version=2018-06-30","***************************”

OK

+QMTSTAT: 0,1 ----------err code = Connection is closed or reset by peer.

Hi @thejaswipatel
If the server needs to verify the certificate, you need to use AT+QFUPL to upload the certificate to the module and bind the certificate through AT+QSSLCFG.
