Error "could not connect to TSM Controller" When Logging in to Tableau Services Manager
Published: 27 Nov 2017 Last Modified Date: 11 Jan 2018
When logging in to Tableau Services Manager (TSM), by running: TSM login –u <username> ; the following error may occur:
"Could not connect to TSM Controller at <hostname>:8850"
Tableau Server on Linux
Confirm port 8850 is open in the firewall, that Tableau Server is started, and the tabadmincontroller process is running on port 8850. For more information, see Configure local firewall in Tableau Help.
The tabadmincontroller process - which handles TSM requests - is installed on port 8850 by default. Either the process is not running, or port 8850 has not been opened in the firewall, or the hostname of the Tableau Server computer has been changed after installation.
