What port does WhatsApp work on - in detail?
WhatsApp is a widely used messaging platform that operates over the internet, specifically using ports to facilitate communication between devices. The primary ports utilized by WhatsApp for its various services are as follows:

WhatsApp Messenger: For standard messaging and media exchange, WhatsApp uses port 443. This is the same port used by HTTPS for secure web traffic. By employing this well-known port, WhatsApp ensures that its communication can easily pass through most firewalls and network configurations without requiring special permissions or adjustments.
-
WhatsApp Web: When accessing WhatsApp from a web browser, the application also uses port 443 to establish a secure connection. This allows users to send and receive messages directly from their computers while maintaining the same level of security as the mobile app.
