Device Is Offline or Last Heartbeat Shows "Never"
If your Swivel Sync device is not coming online, or the Last Heartbeat shows never after 30 minutes, this typically indicates a problem with the device's internet network connection.
Work through the following steps in order:
Confirm the device is powered on. The white indicator light on the front of the device should be lit. If the device is off (e.g. due to a power outage), turn it back on.
Verify the device is connected to an active internet port. Confirm the ethernet cable is securely connected from the Swivel Sync device to an active port on your wifi router.
Verify the serial number entered in Swivel matches the device. Locate the serial number on the bottom of the device and compare it against the serial number entered in Swivel Sync > Device. The serial number is case-sensitive.
Confirm the network firewall allows the required outbound traffic. If the device is connected to an active internet connection but is still offline, your network firewall may be blocking the connection. Share the Network Firewall Requirements below with your internet network provider or IT team.
🔍 Tip: You should see a heartbeat within 30 minutes of plugging in your Swivel Sync device and entering the serial number. If your device has been online previously and recently went offline, the most common cause is a power interruption or a network change on your side.
Network Firewall Requirements
For the Swivel Sync device to function correctly, your network must allow the following outbound connections from the device.
Minimum Requirements
Protocol | Port | Direction | Purpose |
TCP | 80 | Outbound | Standard HTTP communication |
TCP | 443 | Outbound | Secure HTTPS communication |
UDP | 4242 | Outbound | Device synchronization service |
Minimum Requirement: All three ports must be allowed outbound from the network.
Optional: Restricting Traffic to Specific Destinations
If your IT or security policy requires limiting firewall rules to specific destinations, you can configure the firewall to allow traffic only to the following endpoints.
TCP 80 / 443 | Allow outbound traffic to: https://swivelcrm.io |
UDP 4242 | Allow outbound traffic to the following IP addresses:
