Custom Domain Fails with an Error Despite Successful Verification

An error occurs when accessing a custom domain from an internal network. This issue persists even after the domain is successfully configured and verified in the dashboard. The dashboard test for the custom domain returns a successful result. When the custom domain is accessed on the local network, an error occurs, and the request does not reach the tenant.

• Custom Domains
• Native Applications

1. To diagnose the issue, attempt to make a request to /authorize using the custom domain from a location outside the internal network.

2. If the external request is successful, it confirms the domain is being blocked by a local network configuration.

3. Add the custom domain to the allowlist of the firewall or VPN.
