Follow one of the quick start/how-to guides I uploaded my custom html (wingtips) file to blob storage.

I then tested that I was able to access the page through a web browser with success.

I then configured the tenant signin/signup policy to use the custom page and the tenant is returning a 404. (using all defaults the tenant works fine)

Thanks,
Chris
