Enabling both ngrok and the web interface, will disable the option to generate a self-signed HTTPS certificate as it will use the SSL certificate provided by ngrok. Additionally, the installer will not show the options to configure ports.
Using ngrok and the native client access requires an ngrok subscription. Using the free version still gives access to the web interface and RDP, SSH or Telnet to remote endpoints.
ngrok tunnel capability is included in Devolutions Gateway, downloading and manually launching a tunnel with ngrok.exe will not allow Devolutions Gateway to start.
