Communicating with the Internet

Tableau Server on Windows now includes Tableau Services Manager (TSM), which replaces the Configuration Utility and the tabadmin command line tool. If you need help for an earlier version of Tableau Server, see the Tableau Help page.

In most enterprises, Tableau Server needs to communicate with the internet. Tableau Server was designed to operate inside a protected internal network. Do not set up Tableau Server directly on the internet or in a DMZ. Instead, communications between your network and the internet should be mediated using proxy servers. If the computer running Tableau Server cannot access the internet directly, then you may need to deploy forward proxy servers to mediate traffic from inside the network to targets on the internet.

For inbound traffic, we recommend running Tableau Server behind reverse proxy servers.

How Tableau communicates with the internet

Tableau Server requires outbound access to the internet for these scenarios:

  • Working with maps. Tableau uses map data that is hosted externally.

    Tableau Server needs to connect to maps.tableausoftware.com using port 443. If it cannot make this connection, maps may fail to load. You can test connectivity by accessing the Miami and Havana (blue water) map.

    This is the URL:


  • Licensing. Tableau products connect to the internet to activate product keys. Unless you activate Tableau software with the Offline Activation Tool, all Tableau products must have continuous access to the internet to validate their licenses.

    Tableau Server needs to connection to the following internet locations for licensing purposes:

    • licensing.tableau.com:443

    • atr.licensing.tableau.com:443

    • o.ss2.us

    • ocsp.rootg2.amazontrust.com

    • ocsp.rootca1.amazontrust.com

    • ocsp.sca1b.amazontrust.com

    • crt.sca1b.amazontrust.com

    • crt.rootca1.amazontrust.com

    • ocsp.sca0a.amazontrust.com

    • crt.sca0a.amazontrust.com

    • ocsp.sca1a.amazontrust.com

    • crt.sca1a.amazontrust.com

    • ocsp.sca2a.amazontrust.com

    • crt.sca2a.amazontrust.com

    • ocsp.sca3a.amazontrust.com

    • crt.sca3a.amazontrust.com

    • ocsp.sca4a.amazontrust.com

    • crt.sca4a.amazontrust.com

    Requests to the above domains may be on port 80 or 443.

    If Tableau Server cannot make a connection while attempting to activate its license, you will be prompted to do an offline activation.

  • Working with external or cloud-based data.

Tableau Server can run without internet access. For more information about deploying Tableau Server in organizations without access to the internet, see Install Tableau Server in a Disconnected (Air-Gapped) Environment.

In many enterprises, users also need to access Tableau Server from outside the network (that is, from the internet). For example, in many enterprises, users want to be able to reach Tableau Server from their mobile devices in order to interact with views that are stored on the server. To configure access to Tableau Server from the internet or from mobile devices, you should use a reverse proxy. See Configuring Proxies for Tableau Server.
