There might be a problem starting up EC2 Spot Instance in your account due to AWS Service Limits.

Check if your compute cluster is up:

1. Navigate to the EC2 Service in the AWS Console.

2. Click Instances (under Instances) in the navigation pane.

3. Type upsolver-data-updates in the Search bar and click Enter.

4. If you have multiple compute clusters and you want to check if a specific compute cluster's instances are up, type cluster_name in the Search box.

5. Click cluster_name under tag keys to view a menu containing the names of Upsolver clusters that are running in your AWS Account.

6. Click a specific cluster name and verify there are items in the list for that specific cluster.
