Hi @anjanaprasd, The annotations you are using in your Ingress resource are processed by the ingress-nginx project and does not relate to the ingress controller in this project Can you please provide the version of the ingress controller you are running? |

nginx.ingress.kubernetes.io/proxy-read-timeout: "3600"
nginx.ingress.kubernetes.io/proxy-send-timeout: "3600"
