  • It is not possible to restart the nginx service:

    # service nginx restart
    Unable to start service: Unable to manage service by nginxmng: ('start', 'nginx'). Error: ERR [util_exec] proc_close() failed ['/usr/local/psa/admin/bin/nginx_control' '--start'] with exit code [1] Error occured while sending feedback. HTTP code returned: 502 Error occured while sending feedback. HTTP code returned: 502 Can not start proxy server:

    CONFIG_TEXT: nginx[21730]: nginx: [emerg] bind() to 203.0.113.2:443 failed (98: Address already in use)

Cause

The nginx service was not stopped correctly.

Resolution

  1. Connect to the Plesk server via SSH.

  2. Re-enable Plesk nginx proxy using these commands:

    # /usr/local/psa/admin/bin/nginxmng -d
    # /usr/local/psa/admin/bin/nginxmng -e
