No longer receiving connections to Webhook from Wix

I suspect this is a Wix issue but just checking in case anyone knows any different. Today, Wix have stopped being able to connect to my Make.com webhook on the https://hook.eu2.make.com/ URL.

So the issue is Wix can’t establish a connection to https://hook.eu2.make.com/ but are claiming no issues on their side. In Make, I the Webhook (as fas as I can see), isn’t being hit to trigger the scenario.
