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.
