# Troubleshooting Tableau Server on AWS

## This is archived content

Deployments on public clouds continue to be supported but the content for third-party public cloud deployments is no longer updated.

For the latest Tableau Server deployment content, see the [Deploy](https://help.tableau.com/current/server-linux/en-gb/install.htm) section of Tableau Server help.

For those customers who have access, we recommend Tableau Cloud. For more details, see:

## Introduction

Follow the suggestions in this topic to resolve common issues with Tableau Server when installed on an Amazon EC2 instance in the AWS cloud.

- **TSM CLI does not work from additional nodes**
    
    The TSM cli is designed so you can run tsm commands from any node in a server cluster by including the `-s` option to specify the name or IP address of the initial node. The following symptom might occur when running TSM commands from multiple nodes in AWS:
    
    - When running a tsm command with the `-s` option, a message can display:
        
        `Unable to verify the server's HTTPS certificate.`
        
        To run TSM at the command line from any node other than the initial node, you need to use the `-s` switch and the private IP address of the initial node.
- **Tableau Server does not use all CPU cores**
    
    One or more of the following symptoms might occur when working with Tableau Server core-based licensing:
    
    - When installing Tableau Server, the installer might show fewer cores than you would expect to see for the computer running Tableau Server.
    - On the Licences page on Tableau Server, the number of cores listed under Licences in Use is less than you would expect to see.
    - When you run `tsm licenses list`, Tableau Server might report fewer cores in use that you would expect to see.
    
    For more information, see [Not All Cores Recognised by Tableau Server](http://kb.tableau.com/articles/issue/not-all-cores-recognized-by-tableau-server?lang=en-gb).
- **There is high I/O latency**
    
    Changing the disk driver performance setting to **Better Performance** may give you better results.
