Unable to start cloud shell

Question

Since few days I am unable to open cloud shell at all, it says InvalidSubscription. I verified my subscription is active and I am under the correct tenant but still it keeps failing every time with the same error. Tried signing out, clearing cache, and no luck.

Answer 1

Hello Anas Al Shalabi, You’re encountering the error: {"code":"InvalidSubscription","message":"Invalid subscription identifier provided."}. This means Cloud Shell cannot validate the subscription ID it’s trying to use. Even though your subscription is active and you’re under the correct tenant, Cloud Shell fails to provision.

Verify the RBAC Permissions: Check Subscription > Access Control (IAM) > View My Access. You must have: Owner or Contributor

Required Resource Providers Not Registered: Go to Azure portal > Subscription > Resource Providers. Ensure these are Registered:

• Microsoft.Storage
• Microsoft.Resources
• Microsoft.ContainerInstance
• Microsoft.CloudShell

If not, please register them.

You can verify that the subscription is visible in Azure CLI, the subscription state is Enabled or the subscription ID matches the one used in the Azure Portal:

az account list --output table az account show

This is a very valid diagnostic step for InvalidSubscription.

• Make sure your target subscription is listed, has “State: Enabled,” and matches the one you’re selecting in the portal.
• If it’s not listed or it’s disabled, that’s why Cloud Shell can’t provision storage.

If the Subscription not Listed

az login

Then recheck:

az account list --output table

 

If the Subscription listed but wrong Subscription Is Default

Set correct subscription manually:

az account set --subscription "SUBSCRIPTION_ID"

Verify:

az account show

Then retry Cloud Shell.

If Cloud Shell previously worked, reset user settings

• Open Cloud Shell.
• Select the Settings (gear) icon in the Cloud Shell toolbar.
• Choose Reset user settings and confirm.
• Reopen Cloud Shell and reselect shell and subscription; then configure storage or ephemeral session again.
