ECS Task running, but I can't access in EC2

Question

My task's status is RUNNING and I can see the image on EC2 instance with docker ps . But when I try to access the public IP and port the browser says that nothing was found. I've alredy set a security group rule to allow access to all TCP ports. What else can I do?

Dockerfile:

FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 5000

ENV PERSONAPI_ConnectionStrings__Database="[db connection string]"

FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build
WORKDIR /src
COPY [".", "personApi/"]
RUN dotnet restore "personApi/personApi.csproj"
RUN dotnet build "personApi/personApi.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "personApi/personApi.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "personApi.dll"]

Task ports:

Answer 1

I finally figured out what was wrong. After some research I discovered that by default swagger only works in development mode, that's why I accessed when executed from Visual Studio but I couldn't access after publish.

So I changed this configuration and published again.
