Sometimes Gunicorn is returning empty body

[jr1221]

I have a Gunicorn server running a Dash/Plotly app. Over the local network I achieve predicatable and stable connection. However, when I remotey connect via a VPN, I intermitently get a closed connection/size mismatch of the response.

This can be reproduced with curl <URL>, where about 60% of the time it returns: curl: (18) end of response with 6969 bytes missing (a 0 byte response). This only occurs over the VPN, presumably due to latency concerns?

Is there anything I can do to debug this further? When I use log_level debug I see the GET requests for both the failed and normal responses, so Gunicorn sees these requests and responds with 200, but the body is length 0 sometimes?

how to reproduce?
