I upgraded my .Net Core 2.1 to 3.1. After upgrade Liveness and Readiness probe to pods failed. Below is my docker file snippet:

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build
ENTRYPOINT ["dotnet", "Web.dll"]

When I check logs of the pod I get below errors:

Unable to bind to http://localhost:5000 on the IPv6 loopback interface: 'Cannot assign requested address'

Liveness probe failed: Get http://yyyy:80/: dial tcp yyyy:80: connect: connection refused

Here is my Deployment.yaml file:
