A client disconnect isn’t inherently an error, it can just indicate an issue. It means what you said, a client disconnected before a response was fully returned.
The question is “Where that issue is happening? On my side? Is it a code related? Or that is something I cannot control?” I guess. Cause using this link over and over again does not show me any kind of error whatsoever.
