MC60 in HTTP used of "AT+QHTTPPOST" receive error: "HTTP DNS error" or "HTTP socket connect error"

IoT Modules GSM Module
1

Hello
I used to use the HTTP POST & READ at-commands with the MC60 module and everything worked correctly.
But now after sending HTTP POST, MC60 response:

  • CME error: 3813
    or
  • CME error: 3815

In the Quectel document: “Quectel_GSM_HTTP_AT_Commands_Manual_V1.4”
For these errors:
3813 = HTTP DNS error
3815 = HTTP socket connect error

What is “HTTP DNS error” and how do I fix it?
What is “HTTP socket connect error” and how do I fix it?

any help would be appreciated.
Thank you

HI
DNS resolution failure means that the dns resolution of the domain name you entered failed. The module needs to send the domain name to the dns resolution server for resolution into an ip address, and then connect to the server by ip

soc connection failure This means that the connection to the server fails. The reason for the failure may need to look at the network log, which is returned on the server, not our application layer can see
