How do I resolve the error 'Access to This Operation Is Not Allowed' while using Gurobi Instant Cloud?

This error is prompted most likely by using an API Key that is no longer valid (perhaps your code is using the credentials of a person who no longer works in your organization).

To resolve this issue, you need to:

1. Log in to our Cloud Manager with a user that is still a contact of your cloud license.
2. Create a new API Key.
3. Download and save the associated license file, which contains the properties CLOUDACCESSID and CLOUDKEY, among others (you may need to set the environment variable GRB_LICENSE_FILE to point to the target location). Alternatively, you can provide the access ID and the secret key programmatically by setting the parameters CloudAccessID and CloudSecretKey.
