MC65 https post error

Hi,
I’m using MC65 module with opencpu
We are facing an issue communicating with https post.
After send AT+QHTTPPOST, module response “CONNECT”
but after send post message error 3822 is returned.

<AT send: AT+QHTTPPOST=230,120,120

CONNECT

+CME ERROR: 3822

what is your idea?

The error is defined as RMMI_HTTP_RESULT_ERROR_HTTP_RESPONSE_FAILED

No reply is received from the http server. Check the stability of the http server and then determine the current network status of the module
