HTTP 508 Loop Detected is a server error-class status code defined in RFC5842. The server detected an infinite loop while processing the request (WebDAV).
Server-error responses admit the fault is on the server's side: the request was valid, but the server failed to fulfil it. On the wire, the response begins with the status line HTTP/1.1 508 Loop Detected.
