Django Supervisor FATAl Out too fast, how can I improve?

I am using supervisor in django, my supervisor got an error. my server is on Ubuntu 16.04.2 x64 i use, nginx, gunicortn, supervisor, postgresql.

FATAl Exited too quickly (process log may have details)

...

If you have any ideas how to fix this please let me know your thoughts

This is my dispatcher file.

[program:chart_app]
command = /webapps/chart_app/bin/gunicorn_start
user = chart 
stdout_logfile = /webapps/chart_app/logs/gunicorn_supervisor.log
redirect_stderr = true 
environment=LANG=en_US.UTF-8,LC_ALL=en_US.UTF-8

      

        
        
        
      

    

error in logs
