Button Controller Error 404 The Page requested could not be found

I received this error when attempting to access the button controller.

Error 404
The Page requested could not be found

If you are seeing this screen repeatedly, please contact Support.

I've deleted the controller app and reinstalled. rebooted the Hub. (Yes. It's plugged in and connected to the network. Up to date...)

Thanks
Randall

What address is it navigating to when you click on the button controller app from the app screen? Can you post a screenshot of your app screen and the error?

It goes straight to an error screen:

(ip_addy)^[%20/t/r/n/f]+|[%20/t/r/n/f]+$/g

Thank you

So... It looks like it has to due with my browser? Safari does not work, but all is good in Chrome for Mac...
