Problem Launching Webserver, Windows 10

1. run `./manage start `in the von root folder
2. All docker processes start up
=> after a short time the webserver process exits with the error:
webserver_1 | /home/indy/.pyenv/versions/3.6.9/bin/python: No module named server.server

All the other 4 nodes run fine on Windows 10.

I am running unbuntu 16.04 linux on Windows 10 with Docker toolbox/Oracle VM Virtualbox

Start with ./manage start from the repository root and inspect the webserver container output, especially the reported Python 3.6.9 import failure for server.server. Compare the webserver setup with the four nodes that start successfully and verify the behavior under the reported Windows 10, Ubuntu 16.04, and Docker Toolbox environment. Done means the webserver remains running and its module loads successfully.
