504 Gateway Timeout
Published in Networking.
The 504 status code, or Gateway Timeout error, means that the server is a gateway or proxy server, and it is not receiving a response from the backend servers within the allowed time period.
This typically occurs in the following situations:
- The network connection between the servers is poor
- The backend server that is fulfilling the request is too slow, due to poor performance
- The gateway or proxy server’s timeout duration is too short
