Hello Khushboo Kumari

The error message "The connection to data plane failed" indicates that there is a problem with the network connection between your client and the Azure Key Vault. This can be caused by a number of things, including:

• A firewall rule that is blocking traffic to the Azure Key Vault.
• A DNS issue that is preventing your client from resolving the name of the Azure Key Vault.
• A connectivity issue between your client and the Azure Key Vault.

To troubleshoot this issue, you can try the following:

• Check your firewall rules to make sure that traffic to the Azure Key Vault is not being blocked.
• Check your DNS settings to make sure that you can resolve the name of the Azure Key Vault.
• Use a network diagnostic tool, such as ping or tracert, to check the connectivity between your client and the Azure Key Vault.

If you have checked all of these things and you are still getting the error message, then you may need to contact Azure support for help.

Here are some additional things to check:

• Make sure that you are using the correct subscription and resource group for the Azure Key Vault.
• Make sure that you are logged in to Azure with the correct credentials.
• Make sure that the Azure Key Vault is not in a deleted state.

If you have checked all of these things and you are still getting the error message, then you may need to contact Azure support for help.

I understand that you're trying to generate or import a Certificate within your Azure Key Vault but aren't able to due to the above error message. To hopefully point you in the right direction or resolve your issue, I'll share some troubleshooting steps and my findings below.

Troubleshooting:

• Ensure that you don't have any network issues, firewalls, etc., that could be affecting your connection to the Key Vault.
• Based off your error message, refresh your browser to see if that resolves your Key Vault access issue.
• Make sure that your Private Link is correct configured.

Findings:

• If you aren't experiencing any connectivity issues

This error message can also be caused by a Tenant Mismatch - if you recently deployed your Key Vault to a subscription that contains a different Tenant ID, or the subscription that owned the KV was moved to a different Tenant. For more info - The connection to Data Plane Failed.

In order to resolve a potential Tenant Mismatch issue, you can update your Key Vault's Tenant ID. For more info - Moving an Azure Key Vault to another subscription.

Select-AzSubscription -SubscriptionId <your-subscriptionId>                # Select your Azure Subscription
$vaultResourceId = (Get-AzKeyVault -VaultName myvault).ResourceId          # Get your key vault's Resource ID 
$vault = Get-AzResource -ResourceId $vaultResourceId -ExpandProperties     # Get the properties for your key vault
$vault.Properties.TenantId = (Get-AzContext).Tenant.TenantId               # Change the Tenant that your key vault resides in
$vault.Properties.AccessPolicies = @()                                     # Access policies can be updated with real
                                                                           # applications/users/rights so that it does not need to be                             # done after this whole activity. Here we are not setting 
                                                                           # any access policies. 
Set-AzResource -ResourceId $vaultResourceId -Properties $vault.Properties  # Modifies the key vault's properties.

Clear-AzContext                                                            #Clear the context from PowerShell
Connect-AzAccount                                                          #Log in again to confirm you have the correct tenant id

I hope this helps!
