Hello Brian,
Thank you for your message.
Unfortunately, according to our
Support Policy we cannot assist you in resolving network administration issues or issues related to using third-party software. In order to resolve the port forwarding issue please try referring to the ngrok documentation or Support service, as they would be able to provide more insightful information on setting up port forwarding via their software.
Alternatively, please note that instead of port forwarding, it's possible to connect to a remote Host machine located behind a router/firewall via the
Internet-ID connection which is fast and easy to set up.
Hope that helps.
