Thanks to a couple followers for letting me know the link to my Instagram was broken. The widget provider is SnapWidget, and apparently they changed things slightly, so the link stopped working.

As it is now, it looks like the widget will take you to a SnapWidget page for my IG images, rather than to IG itself. If you click one of the images on my widget, you'll go to that image at SnapWidget, with other images alongside.

Hope it works now. Blog owners really have no control over these things, unfortunately.
