How to configure a simple http ngrok tunnel

ngrok.yaml

# Default Location: C:/Users/<username>/AppData/Local/ngrok
version: "2" # Specifies the version of the config file to use.
authtoken: <your-auth-token-here> # Configured in your ngrok dashboard
region: us # Choose the region where the ngrok agent will connect to host its tunnels.

tunnels:
    tunnelname:
        proto: http # Protocol name
        schemes:
          - https # Bind to a specific scheme (http or https)
        addr: https://localhost:3000 # Forward traffic to this local port number or network address. 
        hostname: custom-name.ngrok.io # Any valid hostname that you have previously registered with ngrok (or is available on the domain)
        host_header: localhost:3000 # Required to prevent 3004 Invalid host header error
        
# For More: https://ngrok.com/docs/ngrok-agent/config

Please note that to use a custom hostname you have to have the appropriate ngrok plan. This feature is not available on the free tier.

can confirm it worked for me, thank you so much. I didn't figure out I needed to input the full address in the addr field
