Empty reply from server

[Rike-cz]

I tried to run this example with Docker Desktop in Windows 11 WSL2, but exposed port still return empty response. Curl returned message is curl: (52) Empty reply from server. It looks weird, because server looks to be healthy, compiled and listening on this port (127.0.0.1:8080) and no other application runs there (no port conflict).

Is it the problem of Docker or of this example app?
