The server would not open the channel. The log showed one reason: missing provisioning key for Unified Access Proxy. Without it, no authentication, no routing, no entry. The system held its ground.
A Provisioning Key for a Unified Access Proxy is the cryptographic gate pass that connects your proxy instance to its control plane. It is issued by your management layer and embedded into the proxy configuration during setup. The key enables the proxy to enroll, receive policies, and start authenticating client requests. Without it, the proxy remains inert, isolated.
The Unified Access Proxy acts as a single point of secure entry to internal services. It terminates client sessions, handles identity checks, routes traffic, and enforces policy. Provisioning it correctly ensures consistent trust boundaries across environments.
To create and use a provisioning key, first generate it in your control plane. Store it securely—treat it like a password with elevated privileges. Apply it during initialization, either through environment variables, configuration files, or a bootstrap API. Once applied, the Unified Access Proxy registers itself and pulls down its authorized configuration. Revoking the key immediately severs the proxy’s link to central management.
