Can't create an AKS cluster with Azure Pass subscription

When I try to create an AKS cluster with the portal, I'm facing the following problem:

This problem got "solved" when I scaled-down the cluster to just one node. But when I tried to browse the cluster, it wasn't possible. It was giving me timeouts. It seems that cluster was not health anyway.

Now, when I try to create a new cluster with just one node (A0), it's taking foreveeeeeer! Look:

I'm wondering if there's any special limitation for the Azure pass subscription. But it's weird because when I take a look at the subscription quota, I'm not even close to reaching the limit.

This is a new and clean subscription, I have nothing else there.

So the problem was that I was using an A0 instance type.

AKS cluster nodes need at least 3.5GB of memory, that's why it had errors or took so much time to be created (it never finished actually).

I end up using a Standard A2 v2 (2 vcpus, 4 GB memory)
