Note: If your server is running Linux, stop and start the Apache process. If your server is running Windows, stop and start the IIS service. If you are unable to perform this or are uncertain the server type Plesk is running on contact your hosting provider for assistance.

  • Plesk with Apache Web Server:

1. Click on Server on the left menu
2. Click on Service Management.
3. For the Web Server (Apache) service, click on the green icon. A restart will not work, you must do a stop then start.

  • Plesk with Windows IIS Web Server:

1. Under Main Menu, click on Settings.
2. Under Applications, click on IIS Application Pool.
3. Click on Recycle.

 

10. Your SSL certificate is now installed and should be configured for its website. To verify, use our SSL Analyzer

 

Troubleshooting:

  • Open a web browser and visit your site using https. It is best to test with both Internet Explorer as well as Firefox, because Firefox will give you a warning if your intermediate certificate is not installed. You should not receive any browser warnings or errors. If you immediately receive a browser message about the site not being available, then the server may not yet be listening on port 443. If your web request takes a very long time, and then times out, a firewall blocking traffic on TCP port 443 to the web server.
  • If you receive a "not trusted" warning, view the certificate to see if it is the certificate you expect. Check the Subject, Issuer, and Valid To fields. If the certificate is issued by    Comodo, then the Intermediate certificate is not correctly installed.
