A domain name is the URL or web address where visitors find your site. By default, all Nolt boards are accessible via the Nolt subdomain, shown as [name-of-your-board] You can also use a domain you already own. To perform this action, follow the steps below.

If your DNS provider does not offer SSL with a reverse proxy, please contact us at to setup your custom domain with our automatic SSL service (beta).

1. Add the DNS record

Go to your DNS provider’s website. If this is the first time you are making this choice, select an option that can issue an SSL certificate. Depending on your DNS provider, editing DNS records can take several hours before the changes are applied across the internet.

  • Your connection is not private / Your connection is not secure. Your website hosting / DNS provider has not issued an SSL certificate. If they support SSL, please wait for another few minutes until your certificate is active. If your DNS provider does not provide SSL support, set up a service like Cloudflare in front of it.
