Event routing fails in gateway management after upgrading to cciot-25, causing device data loss

After upgrading our IoT Cloud Connect environment to cciot-25, we’re experiencing critical event routing failures in the gateway management module. Events from IoT gateways are not reaching their configured endpoints, resulting in data loss and broken alerting chains.

The event routing configuration appears intact post-upgrade, but validation logs show endpoint mismatches. We have approximately 150 gateways affected, and our monitoring dashboard indicates a 70% event drop rate since the upgrade.

{
  "routingRule": "gateway_events_to_analytics",
  "status": "failed",
  "error": "endpoint validation failed: target not found"
}

Has anyone encountered similar routing issues after upgrading to cciot-25? The gateway upgrade process completed successfully, but the endpoint validation seems to be the bottleneck.

Thanks for the suggestions. We’re using custom routing rules, and you’re right about the migration utility - we completely missed that step. I ran the utility, and it flagged 47 routing rules with deprecated endpoint formats. Working through the updates now.

I can provide the complete resolution for your event routing failures after the cciot-25 upgrade. This issue stems from three interconnected changes in the gateway management module that require systematic remediation.

Event Routing Configuration Update: The cciot-25 release introduced a new routing rule schema that requires explicit protocol definitions and endpoint versioning. Your existing routing rules are failing validation because they lack these required fields. Run the Gateway Configuration Migration Utility first:

gateway-mgmt migrate-routing-config --source legacy --target cciot-25
gateway-mgmt validate-endpoints --strict-mode

This will identify all routing rules that need updates and generate a migration report.

Gateway Upgrade Compatibility: After the platform upgrade, gateway firmware also needs updating to support the new endpoint validation protocol. The 70% drop rate you’re experiencing indicates that most gateways are still running pre-cciot-25 firmware. Update gateway firmware through the management console:

  • Navigate to Gateway Management > Firmware Updates
  • Select all affected gateways (filter by firmware version < 25.1.0)
  • Deploy firmware package cciot-gateway-25.1.2 or later

The firmware update ensures gateways can properly format events for the new endpoint validation system.

Endpoint Validation Fix: The endpoint validation failure occurs because cciot-25 requires endpoints to be registered with specific attributes:

{
  "endpoint": {
    "id": "analytics_endpoint_01",
    "protocol": "HTTPS",
    "version": "v2",
    "tlsVersion": "1.3",
    "authMethod": "oauth2"
  }
}

Update each endpoint definition in your routing configuration to include protocol, version, tlsVersion, and authMethod fields. The validation engine now performs certificate chain verification and protocol compatibility checks before accepting routing rules.

Verification Steps:

  1. After applying routing config updates, restart the gateway management service
  2. Monitor the event-routing-status dashboard for 15 minutes
  3. Verify event throughput returns to normal levels (check the gateway-metrics API)
  4. Test alerting chains by triggering test events from each gateway

The combination of migrating routing rules, updating gateway firmware, and properly registering endpoints with full validation attributes should resolve your event routing failures completely. Monitor your logs for any “endpoint_validation_failed” errors during the first 24 hours after implementing these changes.

I’ve seen this exact scenario. The 70% drop rate matches what happens when the routing engine falls back to default behavior after validation failures. You need to re-register your endpoints with the new validation schema. Also, verify that your gateway certificates are still valid - cciot-25 enforces stricter TLS requirements for endpoint connections.

We had a similar problem last month. Check if your endpoint definitions were migrated correctly. The cciot-25 upgrade changes the endpoint schema structure, and old routing rules need manual adjustment. Look for deprecated endpoint formats in your gateway configuration files.
