Which port in Tableau Server is fixed and cannot be changed?

The correct answer is that port 443 in Tableau Server is fixed and cannot be changed. This port is used for HTTPS communication, which is essential for ensuring secure data transmission. In the context of Tableau Server, using HTTPS allows users to access dashboards and reports securely over the web, incorporating encryption to protect sensitive information.

It’s critical for Tableau Server to have a standard port like 443 for secure connections, as this is commonly recognized and utilized across various web applications. By standardizing the use of port 443, Tableau ensures compatibility with browsers and adheres to prevalent security practices.

In contrast, other ports such as 80 and 8080 are often used for HTTP and non-secure web traffic, which can be changed according to user preferences. Port 4433 is also not a standard port for Tableau Server and is likely to be used in specific configurations or for other purposes, but it does not hold the same fixed requirement as port 443 for secure web traffic. This distinction underscores the importance of using the correct port as mandated by the security practices of the platform.
