I continuously get this error message when trying to deploy my Django app with Nginx and Gunicorn. I've almost read and implemented all suggestions about this issue on ST.Overflow I've already implemented the following.

1. Ensured there is a shebang: #!/bin/bash

2. Put sh in front of command in /etc/supervisor/conf.d/clouditech.conf

Please find my configuration files

1. /etc/supervisor/conf.d/clouditech.conf

[program:clouditech]
command =sh /home/clouditech/bin/gunicorn_start
user=clouditech
autostart=true
autorestart=true
redirect_stderr=true
stdout_logfile=/home/clouditech/logs/gunicorn-error.log

2. gunicorn_start file

/home/clouditech/bin/gunicorn_start

#!/bin/bash
