Temporarily I am getting 502 bad gateway. its goes off when I reload the page.

Nginx logs files gives:

/code/static/CACHE/css/base.36481a0991d5.css" failed (2: No such file or directory)

I am also getting : """upstream prematurely closed connection while reading response header from upstream, client: server:""" — pythonhmmm

I'm not familiar with cabot. But from the error log it looks like cabot is using django-compressor (not sure). And the CACHE files by django-compressor is not generated yet.

You may need to add an additional step to generate the compressed css/js files.

python manage.py compress
