The app on port 11501 is expecting standard HTTP traffic, but you used https:// .
Things don't always go smoothly. If you're trying to access https://localhost:11501 and encounter an error, here's a structured approach to diagnose and fix the problem.
The address https://localhost:11501, often utilized in 2021, indicates a secure local development environment, frequently associated with containerized microservices, .NET IdentityServer4 testing, or Dapr sidecar setups. Common troubleshooting steps involve trusting self-signed certificates via dotnet dev-certs or using tools like mkcert to resolve "connection not private" errors, or verifying application binding with netstat/lsof for connection-refused issues.

With this configuration, your local server would serve all content, including any resource under the /2021 path, over a browser-trusted HTTPS connection.
Running distributed applications often requires binding specialized background workers to unique port addresses.
