2 out of 4 Health Probes not healthy
I created an Azure Application Gateway.
There are 4 sites, 4 listeners, and 4 rules. I created an NSG and it's associated 1 separate subnet.
When I check the sites with Backend Health are sites are healthy.
When I use PowerShell
Get-AzApplicationGatewayBackendHealth -Name "MyApplicationGateway" -ResourceGroupName "Myrecourcegroup" all 4 sites are healthy.
When I use CLI
az network application-gateway show-backend-health --resource-group "my resource group" --name "My application Gateway" all 4 sites are healthy
However
When I check the probes with check health probes, 2 health probes are healthy, and 2 are not. I get the message to check the NSG or firewall.
What am I doing wrong?
