Issue

When attempting to start or restart Tableau Server, the following error is received:
tabadmin start
===== Starting service...
  *** Tableau Server Gateway requires port 80,
  ***    in use by process 4.
  *** Tableau Server unable to start due to blocked ports.
===== Unable to determine if all components of the service started properly. See "tabadmin.log" for more information.
Status: STOPPED

Environment

  • Tableau Server 2018.1
  • Windows

Resolution

Option 1:

Find the program that is blocking port 80 (like IIS, for example), and install it on a separate system or configure that program to use a port not used by Tableau Server.  For more information, see Tableau Server Ports.

Option 2:

Configure Tableau Server to use a different port as described at Tableau Server Gateway Process.

Cause

The Tableau Server Gateway process uses port 80 to receive HTTP requests.
