Thanks for your reply,

I tested with the commands you given but still the same issue is observed.

Can you provide the full URL? In the meantime I suggest you try it first through POSTMAN

Sorry i can’t share my URL because it is our client’s server. But i tried it with POSTMAN, the data is posting and getting response from the server.

Hi @Swetha_E , I am also getting the same issue.
Could you please tell that your problem got resolved ?
If yes could you provide the sequence of the AT commands for HTTPs post request and also how to generate the certificate.

Would you be willing to share the URL via chat with me? I need to verify whether the HTTPS for EC200U requires additional configuration parameters.
