Port 2083

Technical Overview:

Port 2083 is the default SSL-encrypted port for accessing the cPanel control panel interface via HTTPS. It typically operates over HTTP/1.1 or HTTP/2 secured with TLS protocols, providing encrypted communication with the server. This ensures confidentiality and integrity of data exchanges like user authentication and administrative operations.

Protocols and Functionality:

• Operates over TCP transporting encrypted HTTP traffic.
• Utilized primarily by hosting customers and server administrators to manage hosting operations.
• Supports all cPanel features such as file management, email setup, database management, DNS configuration, and security controls.
• When accessing cPanel through a browser, users are redirected to https://hostname:2083 to invoke a secure session.

Deployment:

Port 2083 is usually opened on managed and shared hosting environments. Systems employ certificate-based encryption, often with Let's Encrypt or commercial SSL providers, to secure the traffic over this port. Hosting providers may also configure firewalls or load balancers to restrict or proxy access to backend cPanel instances.
