Logic app and CRM

Hi,

I created a logic app on Azure.

When I using the Logic Apps Designer and use a blank template, I choose trigger "Dynamics 365 - when a record is created", in the Organization Name drop-down box, I can't find my organization. I manually type in the organization name, then choose from the Entity Name Drop-down box, and it showed "Could not retrieve values. Crm Instance was not found."

I do have a CRM instance, but why I can't choose from the logic app?

Thanks,
