### Where is my Spark URL?

Spark URL is the domain you use to reach Spark on the Web (can also use any URL from Spark once you've logged in) or the endpoint URL of any service you have on Spark.

The Spark URL has the following syntax:

`https://spark.[environment].[region].coherent.global/[tenant]`

This error occurs when attempting to connect to a Spark environment not supported by Coherent Assistant. Please ensure you are using either UAT or PROD environments to log in.
