Did you use "https://www.yourlibrary.beanstack.org"? If so, you want to remove "www" from that URL.
Your site's url is https://yourlibrary.beanstack.org. "yourlibrary" is the subdomain, and there cannot be two subdomains in a web address. For example, you can go to mail.google.com but not www.mail.google.com. Please make sure that you direct people to the correct URL!
