The issue was that I was trying to POST to https when that API actually only supports HTTP. Just leave this as a note for other folks who might run into the same issue.
Any Help can be appreciated
This type of issue comes when you use https instead of http. Change the URL to use http.
Change it to:
This error comes when the API that we are hitting is running on http and we are trying using https. Information was really useful.
Example: Using this https://localhost:8092/customers, when this http://localhost:8092/customers, must be used as API is running on http.
