There was an error deploying your application: java.lang.IllegalStateException: No available Availa

Hello,

I follow training MuleSoft.U Flow Design. When I deploy the application, I get en success message but when I try to start it in order to test as described in the training doc, I get the following error:

There was an error deploying your application: java.lang.IllegalStateException: No available Availability Zones found for region: us-east-2

It seems that this problem is common for training environment but how can I fix it?

Regards,

Francis
