EC20 - Azure Mqtt with CA cert and SSL not working

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.
