I am developing a HTTP protocol with a POST request. However, when I run the element, it went into timeout and in the stream viewer and in the logs I see the following error.

STREAM VIEWER

I tried using POSTMAN to try to reach the end point in the DMA where dataminer is hosting and with POSTMAN it works (status 200 OK) after I set the browser settings to use a proxy server.

Here is the url used in POSTMAN: https://{{HOST}}/api/2.0/sql/statements.

May I know why does the element failed to connect to the end point?

I even used the proxyServer attribute in the HTTP session tag in the protocol.
