ResourceAccessException: I/O error on GET request

[imatulkt]

Hi,
I have installed conductor. I created a simple workflow having a simple HTTP task to call the end point https://datausa.io/api/data?drilldowns=Nation&measures=Population and executed it on my office laptop. It works properly and I am able to get an output.
Afterwards, when I connect to my corporate VPN or any office WiFi and execute the workflow, it fails. I get following exception trace in logs :

ERROR com.netflix.conductor.contribs.tasks.http.HttpTask [] - Got unexpected http response - uri: https://datausa.io/api/data?drilldowns=Nation&measures=Population, vipAddress: null

Can someone help me out. How should I proceed with this? I need to use conductor for workflow orchestration of internal REST APIs that will require Corporate VPN. Am I missing something in my workflow?
