Use same domain for front and backend Net core Angular application

Hello there I have 2 application hosted on the server. 1 angular running with node.js on port 4000 and one net core running trough the kestrel on port 5000. The angular application falls back to index.html I can curl on the server localhost:4000 and get back data The net core application falls back to not found but I can curl on the server localhost:5000/weatherforecast and get back data. Both application have no error in logs. I have 2 virtual hosts for port 80 that are proxying respectively one 4000 port and one 5000 port

however will display only the application on the first virtual host for port 443 the above file in this case 4000 but not both. I can make work one or the other but not togheter. They both work on http curl I am guessing something wrong to this last file virtual host

I pay 10 pound if you help me get site up and running with backend and frontend
