Error 520 when trying to use www

Without www and the IP is working fine. All I have in the DNS records is:

A
www
my IP address
Auto

Am I missing something or is there another issue?

Hello,
Error 520 is essentially a catch-all response when something unexpected happens or when the origin server incorrectly interprets or does not tolerate a request due to a protocol violation or an empty response:
