Issue
Alteryx Service is unable to start
Environment
  • Alteryx Server
    • All Versions
Prerequisites

A valid TLS/SSL certificate has been installed on the Server host machine and Server is configured if TLS/SSL enabled.

Cause

The Alteryx Service is currently running under a service account that is not a member of the local Administrators group. In order for the service to successfully register the required HTTP/S URL reservations, the service account must have administrative privileges.

Resolution

On the Server UI host machine:

  1. Open Computer Management and Press Windows + R, type compmgmt.msc, and press Enter.

  2. Go to Local Users and Groups in the left pane, expand "Local Users and Groups" and click on "Groups"

  3. Open the Administrators group In the right pane, double-click on "Administrators"

  4. Click "Add…" and then enter the username or service account (e.g. DOMAIN\svc_alteryx) being used as the Log On As user for AlteryxService.

  5. Click "Check Names" to validate. If it validates successfully, click OK. Close out of Computer Management.

  6. Attempt to start the service again.
