Attach not working

Issue description:
Ok, admittedly, my setup is a bit weird but it shouldn't matter I think? My project lives on another PC then the one I work with. I use vscode's remote-ssh extension to edit the code and to get Godot to work I just mount the other PC through SSH. This does mean that my debugger lives on another pc than the one that runs the game/editor. With that out of the way, here is the issue:

When I try to attach the debugger to Godot then either nothing happens if Godot runs on another PC despite me having set the correct IP address

If I use an SSH tunnel so I can leave the address field as "localhost" then I get the error: error while processing request 'setBreakpoints' (exception: Object reference not set to an instance of an object).

I don't know where to find more detailed logs about this.

About the logs, you can find them in ~/.vscode/extensions/neikeq.godot-csharp-vscode-0.2.1/dist/GodotDebugSession/GodotDebugSession.log and there may be some more detailed information there. You may want to launch Godot with the --verbose flag as well.

It'd be great if you can also provide the version information of Godot, VSCode, this extension, dotnet SDK, Mono, and anything else that may seem relevant.

I don't use the remote-ssh extension so if you could also provide more detailed steps on how to reproduce this with a minimal setup that'd be great too.

mono and dotnet on the PC that runs Godot:

5.0.202

This project uses F#, but I don't think that that is the issue as I've seen the debugger work before and used it quite a bit before I had to switch to this setup.

Extension version is v0.2.1
vscode is 1.66
MonoDebug is v0.16.2
C# extension is v1.24
Remote - SSH v0.78.0
Ionide-fsharp is v5.12.0

I don't use the remote-ssh extension so if you could also provide more detailed steps on how to reproduce this with a minimal setup that'd be great too.

Step 1: Mount a computer as a drive with a project through ssh. I use spacefm's "connect to server" feature for this.
Step 2: Open godot and have it open the project using the shared drive.
Step 3: Open vscode, install the "Remote - SSH" extension
Step 4: use this extension to connect to the other PC and open the folder with the project
Step 5: After having the SSH extension install the extensions C#, Godot-csharp-vscode and whatever other extensions are needed have it create the launch.json file.
Step 6: Configure Godot to wait for a debugger to get attached (I gave it 10 seconds)

From there, you can either fill in the IP address of the machine running godot in the address part for "Attach" and try to use the attach feature This will result in the problem of the extension trying to do "something" but failing to connect without giving an error.

You can also have the pc with the code make an SSH tunnel to the computer running Godot, forwarding the port that Godot's debugger uses. If you then also leave the address part as "localhost" and try to use the "attach" feature you get the error while processing request 'setBreakpoints' (exception: Object reference not set to an instance of an object) error.

I'm not sure if I am able to give it a go with everything running on 1 PC as this setup has kind of been forced on me due to a combination of bad laptop hardware and not really being able to use a mouse without ending in pain. (Touchpad is somewhat fine thankfully enough...)

About the logs, you can find them in ~/.vscode/extensions/neikeq.godot-csharp-vscode-0.2.1/dist/GodotDebugSession/GodotDebugSession.log and there may be some more detailed information there. You may want to launch Godot with the --verbose flag as well.

I'll check those in a bit. Need to cook dinner first.

the log with just putting the IP address of the PC running godot in the "address" field:

When using the SSH tunnel and "localhost" it also just prints the "Starting debug session" and "Debug session terminated"

00:08:57.676496: GodotDebugSession: Starting debug session...
00:08:58.648266: GodotDebugSession: Debug session terminated.

Looking at Godot's side of thing, in both cases it looks like the debugger can't even get a connection going.
