TEST URL Button not working in Hosting Service admin

[DANMAC909]

There are 3 "TEST URL" on the hosting configuration page that are not working in my shop
These were working before a maintenance upgrade within my version 12 pro
How would I go about troubleshooting this issue?
Thanks

For the test to work a request is sent to one of our servers and then it securely responds to your server. We've recently needed to change the server the test goes to (and therefore the URL). So, for now, the test goes to a URL that is not valid. We'll update the URL in our next release. The failure is not a result of the maintenance upgrade but instead a change on our end that also affects earlier versions of ShopSite.

Currently, you cannot use the test button but can change the settings and do your own confirmation that they work.
