Hi @Oumeima,

Thank you for your question. Let me try to help you!

The error 

Timed out waiting for validation report. Verify that the Ingestion Gateway pipeline is running.

is returned when:

1. The ingestion gateway is not running. It may have failed to start.

2. The validation step is taking too long and is causing the timeout. 

Can you go to your ingestion pipeline and check if it is running?

1. Go to Jobs & Pipelines > Filter the pipeline type for "Ingestion"

2. Find the ingestion pipeline you created. Click on it.

3. Confirm if it is running. If it is not running, click on Start. Wait for it to start and confirm it is not failing.

During startup, it infers the schema of all tables that the user has access to, and not only the 3 you chose.

If it starts successfully, go back and try running the database setup again.

If it fails to start, go to the event logs and look for the errors. You should also check the Driver logs, check the stdout, stderr, and log4j files to get more information about the cause of the error.

You can refer to our documentation here too -> https://docs.databricks.com/aws/en/ingestion/lakeflow-connect/sql-server-troubleshoot

Let us know what you find!
