What does "Some instances cannot be discovered." mean.

I'm just starting out with Azure apps. I have a simple hello world app which works fine if I run it locally. I am having problems when I attempt to deploy on Azure.

Under the App Status Report, I see the following

Some apps are not healthy.

App Status

App Name: spring-app-20220826160101
Active Deployment: default
Status: Some instances cannot be discovered.
Running Instance: 1/1
Registered Instance: 0/1
CPU: 1
Memory: 1Gi

Under Azure services I have

ASP-firstazureapplication-b791 (App Service plan)
first-azure-spring-app (Azure Spring Apps)
first-azure-app-dsnyder (App Service)
insight20220826 (Application Insights)

All are in the same resource group first-azure-application and the same subscription.

I attempted to upload the Java spring application, but I have the above errors. Any suggestions on where to look for the problem?
