HTTP status codes / 5xx — Server errors
WebDAV: infinite loop while processing the request.
The server detected an infinite loop, e.g. recursive bindings during a Depth: infinity WebDAV operation, and aborted.
Inspect the resource hierarchy for circular references.
The fastest way to pin down a 508 is to reproduce the exact request and inspect what actually went over the wire — status, headers, timing and body, without your app code in the way. That is what an API client is for; ReqPad does it from your phone, with every request saved to history.
500 Internal Server Error · 501 Not Implemented · 502 Bad Gateway · 503 Service Unavailable · 504 Gateway Timeout · 505 HTTP Version Not Supported — or the full reference.
Build the request, send it, read status + headers + timing — on your iPhone. Free to start.
