SapUI5 NodeJS ECONNREFUSED in VSCode when running local server

Question

I working in a Microsoft Axure VM with a proxy behind. Proxy is setted up as it would not possible to install npm packages.

Now when running ui5.yaml with npm run start I got this error while localhost is started:

Server started
URL: http://localhost:8080
ApplicationInsights:CorrelationIdManager [
  Error: connect ECONNREFUSED xx.xxx.xxx.xxx:443
      at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1595:16) {
    errno: -4078,
    code: 'ECONNREFUSED',
    syscall: 'connect',
    address: 'xx.xxx.xxx.xxx',
    port: 443
  }
]

local server error

We added IP and port also to firewall but it does not help. Also removed proxy settings but no change of error.

This is also my ui5.yaml.

Has somebody a good idea what I missed?
