The username or password is incorrect when launching Docker from Visual Studio 2019

Question

So, I'm very new to Docker and I'm trying to use it to containerize an ASP.NET (Framework 4.7.2) application. My platform is Windows 10 and the application is to run under a Windows container. Here's what I've done:

1. Click on "Add -> Docker Support..." when right-clicking the project in Visual Studio.
2. Waiting for it to generate a Dockerfile.
3. Clicking "Run".

A generic 500 IIS error pops up when Chrome launches, and it opens at IP 172.26.102.145 rather than localhost:port, like it normally does when running without Docker. I looked at the event logs and this is what I see:

I read elsewhere that the issue may be because of the IP? I ran the following command in Powershell to fetch a different one that I thought would work:

docker inspect <container_id>

But the IP was the same under "Networks/nat/IPAddress".

I also tried disabling firewalls/antivirus as well as logging into my account on Docker Desktop. I'm not sure what I'm supposed to authenticate, my Microsoft login somehow? I feel like I'm making a rookie mistake!

Oh, and here's my Dockerfile:

#Depending on the operating system of the host machines(s) that will build or run the containers, the image specified in the FROM statement may need to be changed.
#For more information, please see https://aka.ms/containercompat 

FROM mcr.microsoft.com/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2019
ARG source
WORKDIR /inetpub/wwwroot
COPY ${source:-obj/Docker/publish} .

This problem turned out to be a red herring, with the real issue found by looking at IIS application logs within the docker container. I suggest anyone facing this to open up powershell in the container by running:

docker container exec -it <container-name/id> powershell

Then browse the application logs with:

Get-EventLog -LogName Application -Newest 15

You may see an issue there. Also, you can try running this in the container to see if an error is spit out:

Invoke-WebRequest http://localhost
