Web site was working then my public IP address changed due to a move

I have update my public IP address here:

And I have created a https certificate for the find-a-tradie.com.au web site using 'Certify the Web' windows software. All good that far.

But I can't access https://www.find-a-tradie.com.au in chrome.

So what settings in IIS do I need to modify to make it work again?
