subdomain | Node.JS Express Subdomain Middleware | Runtime Evironment library

I have swagger (docker: swaggerapi/swagger-ui) running on swagger.mydomain.com with two definitions for api servers running on a.mydomain.com and b.mydomain.com

Both a and b are flask (python) servers. a.mydomain.com had CORS set up for a while now due to serving a webapp on a fourth subdomain. This works fine both on that subdomain, as well as in swagger. Now I did the same CORS setup for b.mydomain.com, however without success.

The setup on both servers looks like this:

My new Macbook Pro running on an M1 Max (ARM) chip just came in. I installed Parallels and Windows 11 Preview for ARM, and Visual Studio installs / launches / builds my solution beautifully. Unfortunately the turn windows features on or off dialog doesn't have the option for installing IIS, and others have posted that this is not supported in Windows 11 for ARM.

Our dev team runs multiple ASP.NET Core 3.1 websites locally under IIS using subdomains, e.g.: https://auth-dev.mydomain.com, https://web-dev.mydomain.com, https://webapi-dev.mydomain.com. This was easy to set up in IIS using the bindings dialog, I could specify for port 443 (https) to use a certain subdomain and our dev SSL certificate.

Now I need to figure out how to make this work on Windows 11 ARM. Developing on an inferior non-Macbook Pro laptop doesn't seem like a great solution for .NET devs, I have to assume others with M1 chip Macbook Pros have run into this same issue. What are my options?

I first started looking into using IIS Express, but it seems like every website has to run on a different port, whereas I need them all to run on port 80 (just with different subdomains.) I'd be fine with them running on different ports if there was a way to forward those various ports to the subdomains, but it doesn't seem like the windows HOSTS file supports that.

I also looked into using the Apache web server for Windows, but I read somewhere that it doesn't support running ASP.NET Core apps.

I want to set wildcard subdomain for my project, using k8s, nginx ingress controller, helm chart:

In ingress.yaml file:

I have an app with postgres as db, sequelize, and express, and whenever it receives a db query, it just stays there forever, no logging or anything I run postgres in a container which I can connect to through GUI normally When I swapped it for sqlite, it worked perfectly the application

here is the relevant piece of code

I have the following configuration in my sites-available (with a symbolic link to enable):

With the eminent demise of the u2f api, I'm trying to move to WebAuthn APIs using the AppId extension to support security keys previously registered with U2F. As best I can tell from reading the docs I think I am doing it correctly, however, when attempting to authenticate I am prompted by my browser to tap my key, and my key is blinking, but upon tapping it I get the error "You're using a security key that's not registered with this website". In comparing the existing u2f authentication request I'm using the same appid and key handle.

Example U2F sign request:

I am struggling to generate a list of substrings from a given list of strings.

Before I begin let me say that I read thoroughly all the stack overflow posts and resources in the appendix, and could not find a solution to my problem.

I am trying to create, validate and connect a subdomain through Route53 and AWS Certificate Manager. The subdomain is challenge.sre.mycompany.com.

The terraform plan looks something like this:
