404 error when requesting http://[your host name:3344]/webapp/?config=config.json

[AndrewTerwiel]

Can anyone suggest some possible causes for a 404 error when requesting  http://[your host name:3344]/webapp/?config=config.json ?

​I'm not sure about the 404, but some tricks for fixing 400 errors Tips and Observations for getting Web AppBuilder - Developer Edition Installed     Not sure if they would be related.  Steps 3h and 3i seemed to solve problems for others.

Andrew,

    The possible correct urls would be "http://[your host name:3344]/webappviewer/?config=config.json" to test your app just using the default stemapp or "http://[your host name:3344/webappbuilder/?id=app num" to bring up your app in WAB for configuration.

Dude! Thanks so much. The webappviewer URL worked.
