I'm trying to test my React application on a mobile device. I'm using ngrok to make my local server available to other devices and have gotten this working with a variety of other applications. However, when I try to connect ngrok to the React dev server, I get the error:
Invalid Host Header
I believe that React blocks all requests from another source by default. Any thoughts?
I'm encountering a similar issue and found two solutions that work as far as viewing the application directly in a browser
ngrok http 8080 --host-header="localhost:8080"
ngrok http --host-header=rewrite 8080
obviously, replace 8080 with whatever port you're running on
this solution still raises an error when I use this in an embedded page, that pulls the bundle.js from the react app. I think since it rewrites the header to localhost when this is embedded, it's looking to localhost, which the app is no longer running on
