Problems connecting to gateway from the get-go

I wanted to introduce Power BI to our organization but before that I wanted to prepare a Proof-of-Concept of sorts so I tried setting up Power BI by signing up for the PRO free trial first.

I made a tabular report as a test and published it when I get the message that I needed a gateway.  So I then downloaded both personal and standard gateway installs but I get stuck on the login part.

Login Error

I get the same error when trying to login using standard gateway.  The problem is the error is not informative.  Do I need to open some ports, is my trial account setup incorrectly?  I just needed a slight push in the right direction so that I can move on to the next step.  thanks.

Network request returned unexpected error.
