Here's why your domain doesn't work with www.

If you can access your website using your domain without "www." but with "www." it won't load, most likely you need to check your DNS zone settings to see if you have an "A" record for "www" entry of your domain.

The "A" record should point to the same IP as your default main domain. You can also setup CNAME record: "www IN CNAME yourdomain.com"
