Summary

The error code 502 on a network device indicates that the server is unable to communicate with the gateway due to a configuration mismatch. This is often caused by an incorrect or incomplete static gateway table. The specific issue stems from the web server attempting to route a request through the default gateway (0.0.0.0), but the system's local network configuration does not contain this address. Consequently, traffic is dropped, and the browser shows a blank page or a red "Connection failed" message, preventing data transfer. The error message suggests that the server is waiting for the gateway to respond but is receiving a 502 error, which often triggers an alert because the gateway cannot return a 200 response code. It is critical to verify that the local router IP matches the gateway IP on the network side, or the gateway IP is incorrect.
