Archive links bring to homepage instead of the article list for the month. Any help?

Hi

I'm using Divi so at the beginning looked like a Divi issue but the tecnical support helped me to understand that is a problem related to something different

I've changed the theme to a default one with a sidebar

I've put the archive widget into the sidebar area

but still, the same problem!

All the links from the archive list months like /2020/12/ bring me to the homepage

What am I doing wrong?

thank you in advance
