Question

Hello.
One step of the pipeline is to deploy the application and the AzurePowerShell@task is used for that. 
`azureSubscription` is provided and being used to access/deploy to  the resources in subscription. 
During the deployment we do: 
`New-AzStorageContext -StorageAccountName <accountName> -UseConnectedAccount` to get the storage account context with the connected account so it would start using OAuth to authenticate. 

However depending on the time when the command is called it fails or not. 

There are two scenarios: 
- 1
   - On start of pipeline create context
   - sleep for 30 minutes
   - create context 
   - access resource 
- 2
   - sleep for 30 minutes
   - create context 
   - access resource 

The scenario 1 works without problem. 
Scenario 2 fails everytime with: 
`Failed to fetch storage account context: ClientAssertionCredential authentication failed: `

Could you please share if this is something expected? 
I assume this is related to the token lifetime, if so how do I reauthenticate again within the same script? 
Thank you in advance!
