Symptoms
Symptoms vary by configuration and environment.
Causes
- Incorrect client or server configuration
- If the address changed unexpectedly, confirm whether DHCP is in use and whether the device obtained a new lease after reboot
- Network reachability or routing differences
- Traffic blocked by firewall rules
Suggested solutions or troubleshooting steps
- Confirm the device and client can reach each other on the network.
- Verify required ports are permitted for the feature in use.
- Test on the same subnet to isolate routing or VLAN effects.
Fix
- If using DHCP, confirm a DHCP/BOOTP server is present and reachable on the LAN.
- Check for IP address conflicts, a duplicate IP can force fallback behavior.
- If DHCP is not available, switch the device to static IP mode.
- Reboot the device and rediscover it after changes.
