robotframework-requests: Host not responding error with https (same host works with http)

Hi,

I am trying to use this library for automating the tests of our rest api.

It works well for http requests. But when I try to use https (unverified, self-signed certificates), I run into the following issue:

The following is my test case:

    Should Be Equal As Strings              ${resp.status_code}    200

To troubleshoot, I tried to manually run the “create_session” method and “get_request” method with appropriate arguments in the python interpreter and there I get a 200 response.

Could you please help identify what’s going wrong here?

Thanks
