LAB 1 - Create New VM validation error

Hello!
As part of the Lab Exercise1 of the OPNFV Fundamentals course, I have to create a Virtual Machine on Azure portal using the aarna opnfv image from the aarna opnfv resource group, which I had to fill a Google form to get access after 24h.
However when I try to create the VM using the mentioned opnfv resource group and image, the following validation failed error message is displayed:
{"code":"AuthorizationFailed","message":"The client '[email protected]' with object id 'acbedab6-7d76-45f1-b85e-c81f205afed6' does not have authorization to perform action 'Microsoft.Resources/deployments/validate/action' over scope '/subscriptions/08f4b432-73a9-48f4-a33c-c550d6057857/resourceGroups/aarna-opnfv-resource-group-00/providers/Microsoft.Resources/deployments/CreateVm-aarna-opnfv-iruya-90-pub-09232020-00-20210115101215' or the scope is invalid. If access was recently granted, please refresh your credentials."}

Hi Tarcisio,
I guess you should select your own Azure Account Subscription & ResourceGroup and you should not select resource group aarna-opnfv-resource-group-00.
Can you please refer to the attached PDF document to find the steps to resolve your issue. Please let me know if still have any further issues.

Vivek
Thanks Vivek,
However I notice that on the aarnanetworks.com directory I cannot use my Azure subscription 1 to create a new Resource group for myself, and when I switch to my primary directory I lose access to the aarna-opfnv image.
Image 1 is my main (Ericsson) Directory.

Image 2 is aarna's directory.
Hi Tarcisio,
This one seems to be some thing to do with your Azure account privilege. Can you please refer to the below links to see if it helps you.
