Google Chrome Developer Tools : Android Debugging returns HTTP/1.1 404 Not Found. Why?

Question

This was working fine up until yesterday. Now when I connect my Android device for USB Debuggers. Chrome is no longer display my app.

Now the popup window shows HTTP/1.1 404 Not Found.

Looks to be connecting fine and the app runs fine on my Mobile Device.

Answer 1

Solution was to access through chrome://inspect/#devices

Then select the "inspect fallback" option.

This is because the remote browser was newer than the client browser.
