I am on ngrok's free tier, v3.0.3, and trying to start a tunnel using ngrok http --domain=xx-xx-xx.ngrok-free.app 80
But I get the following error: "unknown flag --domain".
Would anyone know why?
PM from ngrok here. As mentioned by @Elias Soares, upgrade to the latest version of ngrok which at the time of this post is 3.3.5. If you can't upgrade (which you should), try using --hostname
instead of --domain
.
