Needed: Secure Websocket Echo Test Server

[TheZorch]

I've got a close associate who is writing an application in C# and this application connects to a remote server via wss. However, the server which the app will connect does not have a public echo server. This is needed to test the code, and we have a few requirements.

• First, the echo server needs to accept secure connections wss (self-signed will work just fine).
• It needs to handle multiple channels per application (i.e; multiple connections at once).
• Isn't written in Python, hopefully looking for a canned solution we can run locally on a Windows server or within Ubuntu on Windows.
• Needs to be either free or very low cost if there is a fee/subscription.

We've been searched the web for 2 days looking for a solution that doesn't require working with Python code, which we don't know. Or, solutions that don't cost an arm & a leg. We're not a big company with bottleless coffers. Given how prevalent websocket development is, I'm surprised there isn't a solution out there, or is it that people simply roll their own. If you can help, thank you.

This might do the trick?

Otherwise, you should be able to create your own in C#
