Unit gunicorn.service entered failed state. gunicorn.service failed

Создаю конфиг Юникорна с такими настройками:

[Unit]
Description=gunicorn daemon
After=network.target

[Service]
User=htmlcms
Group=htmlcms
WorkingDirectory=/home/htmlcms/sites/mysite
ExecStart=/home/htmlcms/sites/mysite/env/bin/gunicorn --workers 3 --bind unix:/home/htmlcms/sites/mysite/mysite1.sock mysite1.wsgi:application

[Install]
WantedBy=multi-user.target

Но после запуска получаю следующее:

● gunicorn.service - gunicorn daemon
   Loaded: loaded (/etc/systemd/system/gunicorn.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Wed 2020-05-20 15:49:02 EEST; 10s ago
 Main PID: 26307 (code=exited, status=203/EXEC)

May 20 15:49:02 li1043-207 systemd[1]: gunicorn.service failed.

При этом я без проблем запускаю через команду:

gunicorn --bind 0.0.0.0:8000 mysite1.wsgi:application
