Internet Access Requirements
Tableau Desktop and Tableau Prep were designed to operate with access to the internet. For example, Tableau requires internet access to load map views, to load web pages in dashboards, and to process license requests.
Tableau uses common ports (80 and 443) to make internet requests. In most cases, the computer where Tableau Desktop or Tableau Prep is installed and the network it is running on are already configured to allow the necessary access.
If Tableau doesn't have direct access to the internet, make sure that the domains listed in the following table are allowed by the proxy server on the computer where Tableau is installed and in the network firewall (if there is one). Also make sure that the proxy server can access them without manual or pass-through authentication, so that your users do not have to authenticate each time they need to access the internet.
Note: If you publish workbooks and data sources to Tableau Online, you may need to add Tableau Online to your data provider’s authorized list. For more information see Tableau Online IP addresses for data provider authorization in the Tableau Online help.

Beginning with Tableau 9.1, Tableau maps use an SSL connection on port 443.
The domains listed here listen on port 80 and can then automatically redirect to port 443.
Required to register your copy Tableau Prep.
|Discover pane (optional)||
If there is no access to this website, the Discover pane won't show on the home page. If access to the website is disconnected, the links on the pane will be broken.
Note: Tableau doesn't support pass-through or manual proxy authentication, so it can't pass your user's credentials to a web proxy. If your users have to authenticate to the proxy, or if you have the ports or addresses blocked in the firewall, you must add the domains shown in the table above to your allow list for your proxy and firewall for Tableau to make internet requests to them.
If the maps domain or ports are blocked, you can use offline maps instead. For more information, see Select Background Maps in the Tableau Help.
Enabling internet access for licensing is optional. If the licensing domain is blocked, the licensing activation process prompts for offline activation, which does require access to the internet using a different computer. For more information, see Install Tableau Desktop.
If the licensing domain is blocked and Tableau Desktop was activated offline, the upgrade process requires an updated product key. For more information, see the "Activate Tableau Desktop Offline (if needed)" section in Install Tableau Desktop.
When Tableau Desktop encounters unforeseen circumstances, it might exit unexpectedly. If a crash occurs, log files and dump files are produced to capture detailed information to help Tableau engineers debug the issue. The next time Tableau Desktop is opened, the user is given the option to automatically upload the log and dump files.
However, if you work in an organization that is subject to data privacy regulations, you might not want your users to be able to upload the log and dump files. In those situations you can disable the crash upload prompt from showing. For information about how to disable the crash upload prompt for your users, see Change Installation Settings after Installation.
Tableau Public needs access to the following domain and port:
To test whether firewall and proxy settings are configured correctly and whether a computer has the internet access that Tableau needs, try the following links on a computer where Tableau Desktop is installed:
If the configuration is working, these links produce a map of Miami and Havana. However, if you don't see a map of Miami or Havana or if your test passes only because you manually entered user credentials, you will either need to change the network settings or you users will need to work offline.
In some cases, if you or an IT administrator is not able to change the web proxy or firewall configuration settings to allow Tableau to access the sites it needs, your users can use Tableau offline. Using Tableau offline means that your must perform product activation using an offline process, and that your users use offline maps for the visualizations that require them.
