Symptoms

It is not recommended to change the default Plesk port, however, it can be done using the workaround as below.

Resolution

From version 7.5 Plesk supports two web servers as provider for Plesk Control Panel: IIS and Apache. Depending on the type of web server one of the following ways can solve the problem:

I. Internet Information Services is used as web server for Plesk Control Panel:

When configuring Plesk on port 80 a dedicated IP address must be chosen for Plesk control panel as Plesk Control Panel uses HTTPS protocol for connection and  architecture of IIS allows assigning single SSL port per IP address. By default PleskControlPanel Web site in IIS is configured to listen on port 8443 on all IP addresses. The following needs to be done to change the port:

1. Go to IIS management console

2. Find PleskControlPanel web site

3. Click on Properties

4. Click on Advanced button in Web Site tab

5. Edit SSL identity for the Web Site

6. Set IP address that you want to use and change SSL port to 443

7. Apply

II. Apache is used as web server for Plesk Control Panel:

A dedicated IP address needs to be used for Plesk Plesk Control Panel and none of domains hosted on the server. This is required to avoid conflicts with existing websites. Then edit Apache configuration file %plesk_dir%admin\conf\httpd.conf.

1. Find the line

Listen 8443

2. Replace with

Listen IP_address:443

3. Retsart Plesk Control Panel service using tray monitor.

Additional information

Note: In case of Plesk running on Virtuozzo Virtual Environment , port changing can lead to VZPP-Plesk integration failure.
