same here Kubernetes 1.19.10 Ubuntu 18.04 Docker 19.3.8 Trident 21.01.2

I can reproduce the exact same behavior with the nginx ingress controller using the bitnami helm charts https://github.com/bitnami/charts/tree/master/bitnami/nginx-ingress-controller a workaround which works for me is to set the keep-alive value...

@buchdag at the end its the keepalive_timeout https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/configmap/#keep-alive https://nginx.org/en/docs/http/ngx_http_core_module.html#keepalive_timeout
