How to access Camunda Cloud from inside corporate network

Question

I’m building a PoC with Zeebe

I was able to run from my local pc the Java client at https://github.com/camunda-cloud/camunda-cloud-get-started

Now, when I try to run it from my corporate PC, I’m getting the error below. I understand that I need to fix some network configuration to make it work. Is this configuration documented anywhere?

Many thanks.
