M66 Error code +CME ERROR: 3829

Hello Team

I using quectel M66 module and try send the data to server but getting below error

AT+QHTTPPOST=104,20,20
CONNECT
+CME ERROR: 3829 …Http need relocation

AT+QHTTPREAD=20
+CME ERROR: 3804 … Http get no request

when these error are generated, is it due to NW issue or device issue
