Conditional if can’t display location?

I got the plugin to work and have added shortcodes successfully. I’ve tested it on mobil and other devices and it works great!

But when my boss tries it on multiple devices it won’t display anything where the shortcode is. He is behind a firewall, I’m wondering if that is preventing it from working.

My question is, is it possible for cases like this, for me to display an alternative message if the geolocation isn’t going to return any result.

Thanks,
