Downgrade to gunicorn==0.16.1 resolves that issue but it would be interesting to specify compatible version

[miguelgrinberg]

Did you test any releases between 19.x and 16.1? I'm pretty sure I used v18 at some point and had no problems with it. Release 19.2.1 has been released today, and 19.2.0 was released just a few days ago. I guess there is a chance they introduced a regression.

16, 17, 18 are ok
Since 19 it no longer works

@Yoyoprs that worked great.

pip uninstall gunicorn
pip install gunicorn==18.0

Closing this as it is outdated with the 1.0 release. I have tested gunicorn 19 and it seems to work fine now.
