M95 MQTT Connection problem & QSECWRITE Time out error

IoT Modules GSM Module
1

Hello,I want to connect to the adafruit mqtt server address with the M95 module I use in my project.

  1. I was getting error on query AT+QMTOPEN=0,“io.adafruit.com”,1883 on my first try, so I updated my firmware version with M95FAR03A21.
  2. In my attempt after updating the software, I get a connection lost error as given below.
  3. I get an ERROR error at the command AT+QIDNSCFG=8.8.8.8,8.8.4.4. I cannot connect to the DNS provider I want.
