BC66 QMTSTAT:1,1 Error

Hi,

Previously I was able to connect to IoT platform adafruit.io to publish some results from BC66 module.
Commands used AT+QMTOPEN, AT+QMTCONN, AT+AMTPUB.

But now when I execute AT+QMTCONN, i get a response of QMTSTAT:1,1 which means the mqtt connection is closed by the peer. I even have executed AT+QMTCLOSE and tried again, but still the same.

There is no issue with QMTOPEN. I even tried with firbease and the same still happens.

AT+QMTOPEN returns +QMTOPEN:1,0 requires immediate execution of AT+QMTCONN within 10s

Yes qmtconn is done wtihin 10s, but still having qmtstat:1,1

Please provide the ATlog you tested.

You can see that QMTCONN is done immediately after QMTOPEN, I have also tried to CLOSE and OPEN the connection but same result.
The thing is that this worked before and now it cant.

That this work before and now it cant.

That is, there is an upgrade or encryption or other action on the platform, which causes the device to be inaccessible.

You need to communicate with the platform what is the difference from before.
Or contact the local FAE to instruct you to grab the Genie log of the module end, and we will see the specific reasons.
