[Errno 111] Connection refused - lldb Adapter

[Wickan-lab]

Hello, I was trying out this plugin to see if I could make my life easier, like in vscode :D
However, I get this error when I try to debug a c++ program.

Debugger: error: tcp://localhost:41701 [Errno 111] Connection refused Traceback (most recent call last): File "/home/omen/.config/sublime-text/Packages/Debugger/modules/dap/session.py", line 160, in launch await self.launching_async File "/home/omen/.config/sublime-text/Packages/Debugger/modules/dap/session.py", line 197, in _launch await self._transport.start(self, self.configuration, self.log) File "/home/omen/.config/sublime-text/Packages/Debugger/modules/dap/transport.py", line 120, in start await self.setup() File "/home/omen/.config/sublime-text/Packages/Debugger/modules/dap/transports.py", line 209, in setup raise TransportConnectionError(f'tcp://{self.host}:{self.port} {exception}') Debugger.modules.dap.transport.TransportConnectionError: tcp://localhost:41701 [Errno 111] Connection refused

This is the sublime project config
"debugger_configurations": [ { "name": "C++ (External Terminal)", "type": "lldb", "request": "launch", "program": "${project_path}/build/extractor", "cwd": "${project_path}", "terminal": "console", }, ],

I'm on NixOS 25.05 and the lldb package (lldb_21) is provided by a flake/direnv development environment.

If you run Debugger: Show Protocol there might be some extra information.

Also you could try running the adapter manually Debugger: Browse Package Storage navigate to lldb/adapter then in your terminal ./codelldb --port 8135 (or any port doesn't matter) and see if it runs your system.
