Hi Thomas,
thank you for your kind help.

I'm not sure, due to my lack of knowledge, how I can check if the path from
port 443 to port 8080 works in my app when accessed directly on my system.

ports 80 and 443 seem both listening and owned by nginx.

How can I check if the backend has the capacity to handle the requested
path?
