Sooo... here's a fun situation 🙂
When you update the Azure Traffic Manager monitor config (I've changed the health probing protocol & port - HTTP => HTTPS & 80 => 443) the Traffic Manager looses all of its Endpoints 🙂
Haven't really had time to debug this properly cause it happened on a deploy to PROD, so I've hot fixed it by deleting all the endpoints (we're adding them through a for loop so I've set the limit to 0), and then adding new ones 🙂
I'm using C#
Pulumi version is 2.15.1
Pulumi nuget version 2.7.1
Pulumi.Azure nuget version 3.13.1
