How to configure redirect from Web Server's Default Page or existing domains to the Plesk login page on port 8443 on Plesk for Linux?

Connect to the server via SSH

Create the file /var/www/vhosts/default/htdocs/.htaccess:

# touch /var/www/vhosts/default/htdocs/.htaccess

Add the following content to it using text editor:

CONFIG_TEXT: RewriteEngine On
RewriteCond %{HTTP_HOST} ^203.0.113.2$
RewriteCond %{HTTP_HOST} ^203.0.113.3$
RewriteRule ^.*$ https://example.com:8443/ [R,L]
Redirect 301 / https://example.com:8443/

Note: 203.0.113.2, 203.0.113.3 and example.com should be replaced with public IP addresses and hostname of the server respectively.

Log in to Plesk GUI

Go to Domains > example.org > Apache & nginx Settings

Add the following additional directives:

• If the field Additional nginx directives is present, add the following content to it's beginning:

  CONFIG_TEXT: return 301 https://example.com:8443/;

• If the field Additional nginx directives is absent, add the following content to both fields Additional directives for HTTP and Additional directives for HTTPS:

  CONFIG_TEXT: Redirect "/" "https://example.com:8443/"

Note: example.com should be replaced with the hostname of the server.
