Timeout error when user request URL taping proptocol

Hi, I’m kind of new with haproxy so apologies first.
We use version 1.8.8 as reverse proxy. Everything works fine with one small exception.
When a user writes the URL adding the HTTPS protocol (i.e https://myurl.com) we expect the result to be https://www.myurl.com and load our page, but this is not the case, ending up with an error timeout.
I add a bit of our config hoping that you can give me a guide.

Thanks in advance.
