ConnectionRefusedError: [WinError 10061] when press `F5` to start debugging #10741

BobAnkh · 2020-03-24T12:41:53Z

Environment data

VS Code version: 1.43.1
Extension version (available under the Extensions sidebar): 2020.3.69010
OS and version: Windows 10 1909
Python version (& distribution if applicable, e.g. Anaconda): 3.7.0 64-bit in Anaconda
Type of virtual environment used (N/A | venv | virtualenv | conda | ...): conda 4.8.2

Expected behaviour

The debugger should start and enter a debug session

Actual behaviour

Fail to start the debugger when I press F5.

It first print the following sentence in the terminal:

 $ G:/Anaconda/Scripts/activate

Then pop up the warning:

Then print the following sentences:

$  env DEBUGPY_LAUNCHER_PORT=4625 G:\\Anaconda\\envs\\pytor\\python.exe c:\\Users\\lenovo

    sock.connect(("127.0.0.1", launcher_port))
ConnectionRefusedError: [WinError 10061] 由于目标计算机积极拒绝，无法连接。

The chinese means Unable to connect because the target computer actively refuse

Steps to reproduce:

create a helloword.py with only one sentence print('helloworld')
press F5

Other info I think may be helpful

My launch.json:

{
    "version": "0.2.0",
    "configurations": [
        
        {
            "name": "Python: 当前文件",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal"
        }
    ]
}

My settings.json

{
    "python.pythonPath": "G:\\Anaconda\\envs\\pytor\\python.exe",
    "python.linting.pylintEnabled": false,
    "python.linting.flake8Enabled": true,
    "python.linting.enabled": true,
    "python.formatting.provider": "yapf",
    "python.autoComplete.extraPaths": ["./pytorch"],
}

And, when I add "python.terminal.activateEnvironment": false to the settings.json, the warning no longer appear. But I still prefer to activate environment when starting debugger. Also it seems to ocasionally suceed after several minutes but I don't think it's a good way to face the problem.

The text was updated successfully, but these errors were encountered:

int19h · 2020-03-25T19:47:13Z

You mention that with "python.terminal.activateEnvironment": false, you're not seeing the error message - does this mean that debugger is working fine for you in that case? Or is it failing in a different way?

Also, can you please try adding "logToFile": true to your launch.json, and share all files matching debugpy*.log that you should get in the folder where the extension was installed (something like C:\Users\...\.vscode\extensions\ms-python.python-2020.3.69010)?

BobAnkh · 2020-03-26T05:23:01Z

@int19h
When I add "python.terminal.activateEnvironment": false to my settings.json, the debugger is working fine, which prints helloworld in my helloworld case, though it does not activate my conda.

Here is my debugpy*.log file when the debugger fails to start:

debugpy.launcher-2744.log

debugpy.adapter-9580.log

Hope these may help you.

PS: Is it possible that these problems are caused because I'm using git bash as my terminal? (But I didn't face these problems in previous versions)

Thanks.

int19h · 2020-03-26T06:17:18Z

I can't think of any reason why Bash would make a difference... but other repros that we're seeing are all on Linux, so perhaps it is related. Could you switch to cmd.exe temporarily, and try it with and without activation, to see if that matters?

BobAnkh · 2020-03-26T06:26:36Z

@int19h
I have tried cmd and powershell, and they both work fine in my case, with or without activation. Later I will try to configure WSL to see if it works fine.

BobAnkh · 2020-03-26T08:53:12Z

@int19h
I have tried WSL, and it works fine in ssh remote mode. It fails to start debugger when I just use wsl bash as the terminal (but I think it is due to other reasons not relevant to this issue)

int19h · 2020-03-26T18:43:31Z

Thank you very much - this is incredibly helpful!

I actually have that same issue when connecting to a remote device (using SSH remote), both from my Mac and from my Windows machine.

    sock.connect(("127.0.0.1", launcher_port))
ConnectionRefusedError: [Errno 111] Connection refused

This didn't happen a few days ago. I also don't have a conda environment in this case, I'm using the OS python installation. This happens to be an NVIDIA Jetson device, so unable to easily install conda there.

I have the same issue using the remote development function in Vscode(using ssh connecting mode). Here is my environment:

VSCode Version: 1.43.1
Local OS Version: windows 10
Remote OS Version: Ubuntu 14
Remote Extension/Connection Type: SSH

Steps to Reproduce:

connect to host
debug an arbitrary file(python)

Does this issue occur when you try this locally?: No
Does this issue occur when you try this locally and all extensions are disabled?: No

I can successfully connect to a remote host in Vscode using SSH connecting. And actually I have used the remote debug function for several days. I can still successfully connect to the remote host in the VScode. However, when I try to debug a python file, vscode throw an error as:

  File "/home/lab-lin.ziyao/.vscode-server/extensions/ms-python.python-2020.3.69010/pythonFiles/lib/python/debugpy/no_wheels/debugpy/launcher/__main__.py", line 42, in main
    launcher.connect(launcher_port)
  File "/home/lab-lin.ziyao/.vscode-server/extensions/ms-python.python-2020.3.69010/pythonFiles/lib/python/debugpy/no_wheels/debugpy/launcher/../../debugpy/launcher/__init__.py", line 27, in connect
    sock.connect(("127.0.0.1", launcher_port))

and popup an error window like:

The issue is not removed even I add python.terminal.activateEnvironment": false to the setting.json

zeal-up · 2020-03-31T02:12:54Z

Update:
I finally solve this issue after downgrade the python extension version!
The version causes the issue:2020.3.69010
I downgrade to:2020.2.64397

microsoft/debugpy#84 is the primary issue tracking this bug now, so I'll close this one as a dupe.
