webgl not uploading properly

I get a message saying

“You’ve configured this page to show a html game but you haven’t uploaded the appropriate file!”

I all ready got my webgl build running on Azure but still cannot get it to upload properly to There is not any documentation on configuration or anything, the main stipulation is that there must be a index.html file which Unity creates.

Can anyone point me to the proper documentation and or teach me something new?!

Thanks in advance!

You were probably aploading .rar instead of .zip
