BG96 + MQTT. failed to parse domain name


I am using BG96 module to connect to my server. I am using MQTT to connect.
AT+QMTOPEN = “0”,“”, 1883 works great.
But If I use my server IP address,
AT+QMTOPEN = “0”,“”,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.
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
