Issue with health check URLs on Linux based web apps (python)

Hello we have a Python based web app hosted on Basic B3. The web app has health check configured to a URL "/health"

We have azure AD authentication configured on this application using Easy Auth.

We have also added a Environment variable WEBSITE_WARMUP_PATH set to "/health" as well.

Now we expected the Easy auth to be ignored for the heath check path.

This is working when the app has a single instance.

When we scaled this application to 2-3 instances, stopped the app restarted the app. but the app is authenticating calls to /health endpoint now.

When we scale down to single instance it is working as well.

Could you kindly let us know if there is any way around this.
