VSCode remote debug not working on MacOS

Environment data

VS Code version: 1.20.1 (1.20.1) - MacOS Python Extension version: 2018.1 (01 Feb 2018) Python Version: 3.6.4 on MacOS, 3.5.5 on Armbian (Banana PI M1+) OS and version: MacOS 10.13.3, Armbian 4.14.18-sunxi Mainline kernel ptvsd: 3.0.0 on both MacOS and Server (even tried with the newest one, no change)

Actual behavior

When I launch script with ptsvd on remote server and I try to connect to it from VSCode, I get: Debug adapter process has terminated unexpectedly For internal VSCode log, see attached file vscode - remote debug.log

Expected behavior

Connect to server and start debugging on remote server

Steps to reproduce:

Attach configuration:

    {
      "name": "LowBattery: Remote",
      "type": "python",
      "request": "attach",
      "localRoot": "${workspaceFolder}",
      "remoteRoot": "/home/djmanas/python",
      "port": 3333,
      "secret": "my_secret",
      "host": "192.168.1.101"
    },

Code server.py:

#!/usr/bin/env python3
""" Simple script that will notify user when modules are under certain battery percent """
import ptvsd

ptvsd.enable_attach("my_secret", address=('192.168.1.101', 3333))
ptvsd.wait_for_attach()

print('test‘)

In VSCode, after upload, comment out debug lines.

On server through SSH launch python3 server.py

It waits for attach netstat -lnp

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 192.168.1.101:3333      0.0.0.0:*               LISTEN      30357/python3

Launch the LowBattery: Remote debug configuration and you will get the error.

Does the same thing when I redirect the port through ssh -L 3333:127.0.0.1:3333 and change every IP to localhost.

And should I use ptvsd 3.0.0 or the newest one?

PTVSD version 3.0.0

I didn’t get the message about it, but it haven’t stopped at the print statement.

You need to wait for 5 seconds (remember, there’s a time.sleep). You could reduce that to 1-2 seconds.

Yep. For me it is working flawlesslly, thanks
