IP & Domain Whitelisting

To enable successful communication between the Qntrl cloud and the Bridge instance through HTTPS and WebSocket, your network must allow outbound connectivity to the required domains or IP ranges based on your data center region.

If your organization uses firewall, proxy, or network allowlist rules, share the following domain and IP details with your network administrator before configuring Qntrl Bridge.
