Scenario Conditions
85 Juniper AP43 access points managed by Mist cloud. Rule change blocked TCP 2200 and HTTPS to Mist cloud endpoints. APs continue serving clients with cached config. No cloud visibility or management.
Injected Error Messages (2)
juniper mist cloud disconnection — 85 of 85 AP43 access points showing 'disconnected' in mist dashboard, juniper mist cloud last contact: 52 minutes ago, APs operating with cached WLAN configuration, no telemetry or analytics flowing to mist cloud, juniper mist API returning empty device status for entire site
juniper AP43 access points unable to reach mist cloud — juniper mist channel to ep-terminator.mistsys.net failed, outbound TCP 2200 blocked by recent policy change, APs serving cached SSIDs but cannot receive config updates, juniper mist firmware upgrade queued but cannot be pushed, client onboarding via mist PSK paused
Neural Engine Root Cause Analysis
This appears to be a network connectivity or authentication failure between the Juniper Mist access points and the Mist cloud management platform. All 85 AP43 access points simultaneously showing as disconnected with the last contact 52 minutes ago suggests either a site-wide internet connectivity issue, a problem with the Mist cloud service itself, or a configuration/authentication problem preventing the APs from establishing secure connections to the cloud. The fact that APs are operating on cached configurations indicates they lost their management plane connection but are still functioning at the data plane level.
Remediation Plan
1. Verify internet connectivity from the site's network infrastructure 2. Check firewall rules and ensure required ports/protocols for Mist cloud communication are open 3. Verify DNS resolution for Mist cloud endpoints 4. Check for any recent network configuration changes that might have affected outbound connectivity 5. Validate AP authentication credentials and certificates 6. Contact Juniper support to verify cloud service status if connectivity tests pass 7. Consider manual AP restart if other steps fail
