<Error>No connection could be made because the target machine actively refused it

[itm-platform]

Hi there. I get on CODEMAP EXPLORER No connection could be made because the target machine actively refused it: 127.0.0.1:18002

I opened that port on my firewall, but it had no effect

Any idea of what can be going on?

It means that the syntaxer server (syntaxer.exe) is not running as it should. Why? Hard to say. It's easier to fix it though...

• Close VSCode.
• Kill any instance of syntaxer.exe.
• Start VSCode.

There is a good chance it's all you need

Thanks Oleg. That didn't work. There is no syntaxer.exe running with or without VS Code open.

I have seen a syntaxer.exe in .vscode\extensions\oleg-shilo.codemap-1.10.2\bin which I tried to execute. I got this:

C:\Windows\Microsoft.NET\Framework\v4.0.30319
Probing cscs.exe ...
Probing cscs.exe failed...

Any other suggestion?

The syntaxer server is normally started by VSCode (or any other IDE that uses CS-Script engine for Intellisense).

First you need to see that it can be started without VSCode. Run this:

syntaxer -port:18002 -listen -timeout:60000 cscs_path:C:\Users\<user>\AppData\Roaming\Code\User\cs-script.user\syntaxer\<whatever version you have>\cscs.exe

Let's see if you can start the server then will decide what to do next.

Oh, this worked :)

C:\Users\dpire\AppData\Roaming\Code\User\codemap.user\syntaxer\1.2.1.0>syntaxer -port:18002 -listen -timeout:60000 cscs_path:C:\Users\dpire\AppData\Roaming\Code\User\cs-script.user\syntaxer\1.2.1.0\cscs.exe
C:\Windows\Microsoft.NET\Framework\v4.0.30319
Probing cscs.exe ...
Probing cscs.exe failed...
 >> Server (v1.5.1.0) Started (port=18002)
 >> Syntax engine loaded
 >> Waiting for client request...
 >> Accepted client...
 >> Reading request...
 >> Processing client request

Now I get my map

Any workaround to make it start with VSCode? I already uninstalled/reinstalled

As a side note,\AppData\Roaming\Code\User\ doesn't exist, There is this \AppData\Roaming\Code\User\codemap.user\syntaxer\1.2.1.0

I could not make it collapsable/expandable, though. I will keep trying and open a different issue if I can't make it work Thanks!

• Syntaxer
  Great. It means the all components work correctly and it might be a deployment issue. BTW your syntaxer path is OK. Mine was from the another VSC plugin ("CS-Script"). BTW check if installing "CS-Script" resolves the situation.
  
  Anyway, have a look at https://github.com/oleg-shilo/codemap.vscode/blob/master/src/mapper_cs.ts. This is where starting the syntaxer is implemented. May be it will give you a clue.

• Collapsing
  Try and see if the same C# code as below produces the same effect. Basically I expect only classes to be collapsable:

But you will need to ensure that you have "codemap.textMode": true. See the https://github.com/oleg-shilo/codemap.vscode#limitations section

All good. Thanks Oleg!
