Expected behaviour

Debug session would run

Actual behaviour

Error below

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

1. Remote connect via SSH
2. Click Run and Debug for a Python File containing only a print statement
3. Receive pop-up error:
   Session[1] timed out waiting for <debugpy.adapter.components.missing.<locals>.Missing object at 0x7f530b61c978> to connect

with a terminal error:

env DEBUGPY_LAUNCHER_PORT=34795 /nail/home/rkosko/venv/bin/python3 /nail/home/rkosko/.vscode-server/extensions/ms-python.python-2020.3.69010/pythonFiles/lib/python/debugpy/no_wheels/debugpy/launcher /nail/home/rkosko/repos/shootie/app/test.py

    main()
  File "/nail/home/rkosko/.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 "/nail/home/rkosko/.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))
ConnectionRefusedError: [Errno 111] Connection refused

I believe the debugger should be executing /nail/home/rkosko/.vscode-server/extensions/ms-python.python-2020.3.69010/pythonFiles/ptvsd_launcher.py instead of the debugpy file.
