I have a script task that tries to execute a HTTP request, which seems to work in isolation - when manually clicking on the URL, it will perform the action successfully.
The problem is that when executing the whole task it produced this error :
[HTTP Request Error] Error: An error occurred while sending the request.
Error: The script returned a failure result.
Could anyone assist and help work the problem?
I'm using Visual Studio Pro 2019 with C#2019 Script Language, .Net Framework 4.7.
Below is the full code. Thank you.

* To use a parameter in this script, follow the same steps. Parameters are always read-only.

* Example of reading from a variable:
* DateTime startTime = (DateTime) Dts.Variables["System::StartTime"].Value;

* Example of writing to a variable:

Run the script in debug mode to determine the line which causes the error and to dig deeper into the details of the error.
