Customization of entando-de-app

I’m creating a big project in entando 6.3.2 and I’m receiving this error when i try to upgrade the image and start the entando-de-app

Startup probe failed: Get "http://10.42.0.55:8080/entando-de-app/api/health": context deadline exceeded (Client.Timeout exceeded while awaiting headers)

How can I solve it?
thanks
