BG96 + MQTT. failed to parse domain name

IoT Modules LPWA Module
1

Hi,

I am using BG96 module to connect to my server. I am using MQTT to connect.
AT+QMTOPEN = “0”,“mqtt.hivemq.org”, 1883 works great.
But If I use my server IP address,
AT+QMTOPEN = “0”,“192.58.xxx.xx”,1883
it throws an error ‘Failed to parse domain name’

At this moment not using any certificates. no SSL.

Does any one knows what setting I am missing.

hi ,

There are two possibilities.
The first one is that SNI is not enabled.
AT+QSSLCFG=“SNI”，1,0
The second one is that SSL authentication server and mqtt service have two IP addresses. for more analysis ， we need the capture log to analysis，
pls send email to support@quectel.com
