Error 404 on new controller

But when I try to call the url 
'http://corsoci4.ddns.net/articoli' 
in the log I recived the follow error:
'127.0.0.1 - - [17/Jan/2024:19:21:46 +0100] "GET /favicon.ico HTTP/1.1" 200 5731'.

What do you see when you try to call the url 'http://corsoci4.ddns.net/articoli' ?
The Apache log you showed is not an error.
