I have ngnix server that proxies incoming requests to a docker that has another ngnix running and it forwards requests to a nodejs server. Sometime my nodejs server takes upto 10-15 minutes to respond with a reply. But before nodejs server responds, I get 502 Bad Gateway. I tried to increase ngnix timeout on both the ngnix servers one on the host machine and another on the docker, but it does not seem to work
client_header_timeout 15m;
client_body_timeout 15m;
send_timeout 15m;
proxy_read_timeout 15m;
proxy_connect_timeout 15m;
