Specific Address - there was a problem with your checkout shopify specific address

[BretyboyOO]

I tried to place on order on my store (www.newyorktropicals.net) and receive the message "there was a problem with your checkout shopify specific address", HOWEVER, it only happens when I type one specific shipping address. (2735 Academy Street, Oceanside, NY 11572)  It crashes every single time as soon as I type that specific shipping address. (Try it yourself if you don't believe me, just don't finalize the order)   I have not seen it happen with any other address.  I've used different devices and browsers, same issue.  I need to make sure this isn't affecting other customers and addresses.  I'm new to Shopify and disappointed I'm already running into an issue like this.  Please help.
