"This region has quota of 0 PremiumV2 instances for your subscription. Try selecting different region or SKU"

Answer 1

@auricio Welcome to Microsoft Q&A forum!

As error suggests that "This region has quota of 0 PremiumV2 instances for your subscription" you doesn't seems to have a sufficient quota. Try selecting different region or SKU and let us know if that solves your issue.

As mentioned in the doc, Select preferred storage performance and VM size for your blockchain network. Choose a smaller VM size such as Standard DS1 v2 if you are on a subscription with low service limits like Azure free tier.

Please note that, Quotas are applied per resource group, subscriptions, accounts, and other scopes. For example, your subscription may be configured to limit the number of cores for a region. If you attempt to deploy a resource with more cores than the permitted amount, you receive these kind of errors stating the quota has been exceeded.

Either you can delete the existing resources which are not required anymore or If you want to raise the limit or quota above the default limit, open an online customer support request at no charge.

Hope this solves your issue. Do let us know if you have any further queries.

@auricio Free trial have a set limited amount of resources that you can use. If you have not yet reached or exceeded that limit, it should be enough to deploy Azure Blockchain Workbench. Please make sure your free trial allows you to deploy these services as stated here: Prepare for deployment

• App Service Plan (Standard)
• Application Insights
• Event Grid
• Azure Key Vault
• Service Bus
• SQL Database (Standard S0)
• Azure Storage account (Standard LRS)
• Virtual machine scale set with capacity of 1
• Virtual Network resource group (with Load Balancer, Network Security Group, Public IP Address, Virtual Network)
• Azure Blockchain Service. If you are using a previous Blockchain Workbench deployment, consider redeploying Azure Blockchain Workbench to use Azure Blockchain Service.

Also, as mentioned earlier, If you have already reached a limit, either free up space by deleting other service instances that have exceeded quota or upgrade to pay-as-you-go option.

Hope this clarifies your doubt. Let me know if you need further help.

I deleted all existing resources in a resource group and tried to deploy the workbench again, but it was unsuccessful.

The error is:
{"status": "Failed", "error": { "code": "InvalidTemplateDeployment", "message": "The deployment of the 'newblockchain-M1-appBuilder' model is not valid according to the validation procedure. The tracking ID is 'xxxxxxx-xxxxxxx-xxxxxxxxx'. Check the internal errors for details.", "details": [ { "code": "ValidationForResourceFailed", "message": "Validation failed for a resource. Check 'Error.Details [0]' for more information.", "details": [ { "code": "SubscriptionIsOverQuotaForSku", "message": "This region has quota of 0 PremiumV2 instances for your subscription. Try selecting different region or SKU." } ] } ] }

The first time I deployed the blockchain workbench, only three features failed, so I deleted the features and then tried to deploy again, but one feature fails and the rest are not being deployed.
