503 error after upgrade to 27.1.4

I just noticed a path issue:

The second error (although it shouldn’t be the real problem here) the request

request: "GET /apps/theming/img/background/kamil-porembinski-clouds.jpg HTTP/1.1", host: "10.0.1.100"

should have been

request: "GET /apps-pkg/theming/img/background/kamil-porembinski-clouds.jpg HTTP/1.1", host: "10.0.1.100"
