Connect a custom domain

In this section you will learn how to add a Custom Domain to your application

Connect a subdomain such as app.example.com to the intended app.

Before you start: verify the published app at its existing address and confirm that you can edit the chosen domain's DNS records.

Open domain setup

1. Open More → General.

2. Find Custom Domain.

3. Open its configuration control. For an existing configured entry, use the edit icon.

4. In Connect a domain, enter the exact subdomain without https://.

5. Select Continue and follow the DNS instructions displayed for your app.

6. Review the setup and complete Add Domain when the required configuration is ready.

Connect a domain dialog with a subdomain field, Continue, and Add Domain

Configure DNS using the supplied values

Record the type, host/name, and target/value shown in the setup flow. Enter those values in your DNS provider's controls, accounting for whether that provider expects a full hostname or a subdomain label.

For example, app.example.com identifies the intended hostname; it does not specify a universal DNS target. Use the actual target provided for your app and deployment. DNS update timing varies, so check the configured records and status rather than relying on a fixed delay.

Verify the connection

Return to More → General → Custom Domain and inspect its status.

Open the exact custom address and confirm that the intended app loads. Test sign-in, relevant pages, and a permitted action using an intended account. Review identity-provider callback settings if your authentication flow depends on the app address.

If a check fails, use Troubleshoot a custom domain. For self-hosted deployments, use On-Premise custom domain configuration.
