Schlage Encode: Network Security Blocked - Firewall Fix... | digitalhomefaults.org

Technical Background:

The Schlage Encode communicates over Wi-Fi (2.4GHz). The 'Network Security Blocked' error typically indicates the residential router's firewall is preventing the lock from establishing a secure connection to Schlage's cloud services. This involves outbound TCP/UDP port communication (443, 8883) and potentially DNS resolution issues. The lock uses TLS for secure communication, requiring proper certificate validation. Network Address Translation (NAT) settings on the router also play a critical role.

Symptoms:

The Schlage Encode lock displays a persistent 'Network Security' error within the Schlage app. The lock may exhibit blinking red LEDs indicating a network connectivity issue. The app displays error logs related to firewall restrictions or blocked ports. Remote access to the lock is unavailable.

Possible Causes:

Router firewall rules blocking outbound connections from the lock's IP address or MAC address.
Incorrect DNS settings on the router preventing the lock from resolving Schlage's servers.
Advanced security features (e.g., intrusion detection systems) on the router falsely identifying the lock's traffic as malicious.
Double NAT configuration if using multiple routers or cascaded networks.
ISP-level firewall restrictions implemented by Bell or Rogers (rare, but possible).
Firmware incompatibility between the lock and the router, especially after router firmware updates.

Solution:

1

Access your router's web interface (typically via a web browser) using the router's IP address (e.g., 192.168.1.1 or 10.0.0.1).
2

Locate the firewall settings and check for any rules that might be blocking outbound connections from the Schlage Encode's IP address or MAC address. Temporarily disable the firewall to test if this resolves the issue.
3

Verify that the router's DNS settings are set to a reliable DNS server (e.g., Google DNS: 8.8.8.8 and 8.8.4.4, or Cloudflare DNS: 1.1.1.1).
4

Check for advanced security features (e.g., intrusion detection) and temporarily disable them to see if they are interfering.
5

If using a Bell Giga Hub, check for advanced parental control settings or security profiles that might be blocking the lock's traffic. Consult Bell's documentation or support for assistance. Rogers Ignite users should review their Advanced Security settings via the Ignite WiFi Hub app.
6

Ensure the Schlage Encode has the latest firmware installed via the Schlage app. Also check for any available firmware updates for your router.
7

If the lock has been assigned a dynamic IP address via DHCP, consider assigning it a static IP address on your router to prevent IP address conflicts and simplify firewall rule configuration.

Safety Warning:

Modifying firewall settings can expose your network to security risks. Ensure that you understand the implications of any changes you make. Regularly review and update your router's security settings. Prioritize strong passwords for your router and Schlage app. Protect the physical security of your router.

Prevention:

- Regularly check for and install firmware updates for both the Schlage Encode and your router. - Review your router's firewall logs periodically to identify any blocked connections. - Consider assigning a static IP address to the Schlage Encode. - Before making changes to your router's configuration, create a backup of the existing settings. - If you are unsure about any of these steps, consult with a qualified network technician.

Expert Tip:

Some routers have a 'DMZ' (Demilitarized Zone) setting. While not recommended for permanent use, temporarily placing the Schlage Encode's IP address in the DMZ can help diagnose whether the firewall is the root cause. If it resolves the issue, you can then create more specific firewall rules to allow the necessary traffic without compromising overall network security.

Frequently Asked Questions

•What ports does the Schlage Encode use for outbound communication?

The Schlage Encode typically uses TCP ports 443 and 8883 for outbound communication with Schlage's cloud services.

•How do I find the MAC address of my Schlage Encode lock?

The MAC address is usually printed on a label on the lock itself or in the Schlage app's device information section.

•My ISP (Bell/Rogers) says they aren't blocking any ports. What else could be the issue?

Even if your ISP isn't blocking ports directly, their equipment (modem/router combo) might have default firewall settings enabled. Check the device's settings or contact their technical support for assistance.
