Upload/Convert content ends in 502

[elmaddin22]

Uploading or converting content ends in Bad Gateway.

If i add

proxy_request_buffering off;

to ingress.conf, it works, but the audio file is broken.

I could more or less fix the error by removing the line in nginx.conf

sendfile on;

and in the nginx/servers/ingress.conf line

proxy_redirect off;

This allowed me to upload and convert audio files. However, the error still occurred from time to time
