Nginx service enabled in Plesk is unable to start: Not starting nginx as it is disabled in Plesk.

Symptoms

Plesk Obsidian running on a Linux-based operating system
Nginx web server is down and is unable to start:

# systemctl start nginx
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

The execution of the journalctl -xe command shows the following message:

Not starting nginx as it is disabled in Plesk. Run 'plesk sbin nginxmng -e' to enable nginx in Plesk.

Nginx is shown as already enabled when executing the following command:

# plesk sbin nginxmng -s
Enabled

The Nginx syntax test command shows that there are no Nginx syntax errors:

# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Cause

A misconfiguration in some Nginx configuration files is preventing it from starting. In it unclear how exactly the misconfiguration has occurred, however the configuration needs to be reset by disabling and enabling the connection between Plesk and Nginx in order to resolve the issue.
