My first Excel Office JS Add-in ActiveX issue

I've started experimenting with my first Excel Office JS Add-in but keep getting a security message every time I reload the add-in. I've tried the different options in Excel Trust Center settings with no result. Can anyone help me with this?

Can you double-check what is the URL that you put into your manifest. In particular, is it a https://localhost:XXXXX/ sort of URL?

If I recall correctly, I've seen something similar before when using http (rather than https), and/or when I tried using a file:/// path.

ActiveX is a legacy technology and shouldn't be leveraged by an Office Web Add-in.

Aside from its age, only IE10 supports ActiveX (and its disabled by default) which means any Add-in that uses ActiveX will fail to work in anything other than Office for Windows. All other platforms (Office for Mac, Office Online, Office for iOS, etc.) would be unable to use it.
