HTTP 504 Gateway Timeout vs 508 Loop Detected
Both HTTP 504 (Gateway Timeout) and 508 (Loop Detected) belong to the 5xx Server Error category. 504 indicates that the server, acting as a gateway or proxy, did not receive a timely response from the upstream server. Meanwhile, 508 means that the server detected an infinite loop while processing the request (WebDAV).

When You See It
When an upstream server is too slow to respond within the proxy's timeout window.
How to Fix
Increase proxy timeout settings. Optimize upstream server performance. Check for long-running queries.
Description
The server detected an infinite loop while processing the request (WebDAV).
When You See It
When WebDAV encounters circular references in bindings.
How to Fix
Fix the circular reference in the WebDAV configuration.
Key Differences
HTTP 504: The server, acting as a gateway or proxy, did not receive a timely response from the upstream server.
