Description
I'm using Spring boot within a Docker image on Azure (App Service).
After upgrading from Spring Boot 2.7.7 to 2.7.8 no request reaches the spring container any more, Tomcat responds with 404 to all requests.
The strange thing is that everything is working locally within the IDE as well as when running the Docker image locally: The exact same image with the same env variables as in Azure is running locally.
Within the Azure App Service the application starts successfully, however absolutely no request is processed. Even actuators are not reachable. Tomcat responds with a 404 to every request.
After downgrading my app to 2.7.7 everything works again in Azure App Service. (The Spring Boot downgrade was the only change.)
I attached the logfiles where you can see that the application was started successfully, however there is no more log produced, except from scheduled tasks. No http request reaches the spring container.
