If you experience DNS lookup failures within a custom DNS zone, verify that DNS requests are being received by Jamf's servers and forwarded to the correct DNS resolver in your network.
- Ensure that the custom DNS zone is configured properly in Jamf Security Cloud. For DNS zones being forwarded to your network, edit the configuration to determine which IPsec gateway is being used to forward DNS requests to your network's authoritative name servers.
- Confirm that the IPsec gateway is active and connecting to Jamf Security Cloud by navigating to and reviewing the gateway's status.
- Review the Zero Trust Network Access (ZTNA) DNS logs in Jamf Security Cloud to determine whether requests are being forwarded correctly. You can access these logs by navigating to . To view the IP address of the DNS resolver that provided the response, click the three dots at the top right of the Event logs table and select the Resolver checkbox.
