Hey, your problem matches what I had trouble with. I found a solution and posted it in my thread:

Atlassian Connect-Express setup does not render page

Solved by following this: https://optimizory.atlassian.net/wiki/spaces/KB/pages/500269057/Facing+ngrok+error+6022+even+after+installing+the+auth+token TL;DR: For some reason npm got confused with which ngrok to use.
