Real customer cases， witness our professional service and commitment
After the customer received a shipment of 2,400 smart door locks and 600 smart handle locks, multiple devices failed to pair with the cloud platform during deployment. Symptoms include: devices remaining offline for extended periods, pairing requests being repeatedly rejected, and some devices being discoverable on the same LAN but unable to complete binding. The customer’s network environment uses corporate VPN plus multiple AP coverage. Lock firmware version is V1.2.0; Android and iOS apps are versions 3.4.1 and 3.4.2 respectively. The issue prevents the customer from performing bulk activations and affects installation progress at nearly 10 project sites. At least 90% online rate must be restored within a short time to meet delivery milestones.
1) Remote data collection: Shared a diagnostic toolkit with the customer via a secure channel and collected logs from 100 problematic devices, cloud access logs, DHCP allocation tables from routers and APs, VPN configurations, and corporate firewall policies. 2) Preliminary assessment: Based on logs, most devices complete mDNS/UDP discovery on the LAN but encounter TCP resets or timeouts when initiating TLS handshakes to the cloud; additionally, some devices repeatedly use locally cached old tokens causing the server to reject binding. 3) Remote debugging measures: a. Guided the customer to create a temporary test VLAN on a non-production segment and allow necessary ports on that VLAN (443/TCP, 5683/UDP for CoAP fallback), disable deep packet inspection by the corporate firewall for the target cloud domain, and apply VPN split tunneling to avoid NAT port rewriting. b. Deployed a debug firmware package V1.2.1-hotfix with detailed log levels to 200 devices via MDM bulk push and rolled out a TLS certificate rotation script, cleaning up expired local tokens on devices. c. Added a temporary whitelist policy on the cloud to allow devices to retry binding within a short window while logging retry sources to prevent mismatches. d. Conducted two remote video sessions with the customer's technical team (including screen sharing and on-site network device configuration), observed the pairing process in real time, and adjusted AP multicast/IGMP snooping parameters to ensure stable delivery of LAN discovery messages. 4) Verification and rollback plan: After confirming in the test VLAN that 480 of 500 devices completed pairing and remained stable online, replicate the network adjustments in production in batches; meanwhile prepare rollback firmware and configuration scripts in case of anomalies.
After 72 hours of phased remote support and firmware deployment, 2,160 of 2,400 smart locks and 552 of 600 smart lever locks successfully completed cloud pairing and remained stably online, achieving an overall online rate of 90.8%, meeting the client's short-term delivery milestone requirements. The root cause was identified as enterprise network NAT/deep packet inspection causing TLS handshake interruptions and a device-side token management defect. We have provided the client with a network configuration white paper and firmware fix patch V1.2.2 to complete the final fixes on the remaining devices. The client is satisfied with the response speed and remote collaboration. We recommend performing a pre-deployment network compatibility check and using the latest firmware before large-scale deployments to avoid recurrence.
