"Could not connect to TSM Controller at <hostname>:8850"
Environment
Tableau Server on LinuxResolution
- Confirm port 8850 is not blocked by a firewall and the tabadmincontroller process is running on port 8850. For more information, see Configure local firewall in Tableau Help.
- Confirm the hostname of the Tableau Server computer has not been changed since installation. For more information, see Installing Tableau Server in Tableau Help.
Cause
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.Thank you for providing your feedback on the effectiveness of the article.
