EHS6 SSL Certificate failed verification | Telit Cinterion IoT Developer Community

Hi,

My application uses mqtt client library to establish connection to aws server. The application will re-establish aws connection everytime the connection is lost (due to unstable cellular network). I have noticed that after about 11 or 12 ***** of disconnection, new attempt to reconnect will give exception "IOException Certificate failed verification".

I also stopped the java program, then used AT commands to make connection to aws server. Error was returned as "^SIS: 1,0,200,"error in sendRequest Certificate failed verification"

So far the only way to recover from this error is to restart the module. May I ask what might be the reason for the failure here?

This is the version of my module:

Cinterion

EHS6

REVISION 03.001

A-REVISION 00.000.49

Thank you.

Regards

Thu Hang
