Http read error after http post request

IoT Modules LTE-A Module

I use ec200T-CN module. I tried to post data to server through USB from qnavigator tool. I got proper response from the server. Following is the at commands sent through q-navigator.

But If I send the same commands through uart from stm32, I get success message till post command - which is +QHTTPPOST: 0,200,13. after that If I try to read - server response body - I get +cme error : HTTP(S) no GET/POST requests.
I tried giving delays between - http post and http read - didnt work.
Can somebody tell - where I might have gone wrong ?

Can you provide the corresponding log of STM32?
pls check

AT+CGPADDR
AT+QIDNSCFG=1
AT+QIDNSGIP=1,“https://c0e87952-cfcd-4519-81c7-fb1f9b0a4933.mock.pstmn.io/pst”

when I send the at commands that you have suggested through - q navigator tool I get the following responses:

[2025-01-24 10:42:35:043_R:] AT+CGPADDR

But when I send the same through stm32 - uart - I am not getting any responses. I just get the echo message.
Thanks in advance.
