I tried restarting the NGINX server with `sudo yunohost service restart nginx`, but it failed.

211219_1522_test-fmds_yunohost-service-restart-nginx.txt

admin@test-fmds:~ $ sudo yunohost service restart nginx
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.
Warning: Could not execute the command 'systemctl restart nginx'
Error: Could not restart the service 'nginx'
