Quectel EG95 MQTT problem while opening a network for MQTT client

One of my project Quectel EG95 module using to send the data to AWS server Through MQTT protocol.
Now i am checking with AT commands Manually. All the Certificates store in to RAM After that I sent the AT+QMTOPEN command and every time i am getting response from the module is +QMTOPEN :0,4.
This means “Failed to Parse the Domain” .How to solve this.

I recommend you use the MQtt.fx tool to debug first
mqttfx-1.7.1-windows-x64.exe

We ran into a problem similar to this, and found that our data usage for the SIM had maxed out. Installing a new SIM or upgrading the data plan to support more data fixed the issue.

OK,you are great,We will continue to communicate with you if you have any questions
