If a Private Resource is Served by Both a Tunnel Group and a Connector Group
If both a network tunnel group and a connector group with connectors are properly configured to support a connection, a connector forwards Zero Trust Access traffic by default. If all connectors in the connector group are not reachable, the network tunnel routes the traffic. If the connector group is reachable but the request fails for some reason, traffic will not fall back to the tunnel and the connection will fail.
