I am trying to create an application in IBM Internet of Things Platform Starter and getting following message:
BXNUI0005E: The 'xxxxxx' app wasn't created because a problem occurred contacting Cloud Foundry. Try again later. If you see this message again, go to the IBM Cloud status page to check whether a service or component has an issue. If the problem continues, go to IBM Cloud Support.
I've had exactly the same problem. It's usually because you've gone over the limit of app / database instances for your account.
In my case, I was using NodeRed. I created one instance successfully, deleted it, but then couldn't create another. It turned out that the first app had created an empty database instance and the second one was trying to do the same. Deleting the database from my dashboard resolved the problem.
