Failing to upgrade DxMs

I'm trying to upgrade some DxMs of a self-managed DMA with a cloud connection. Keep getting the following error on the step "RetrieveArtifactInfo":

{
  "errorMessage": "Unexpected exception occurred",
  "exceptionMessage": "Could not fetch blob metadata with ID 'dxm/3d0f033b-4d0d-413d-9eba-a82e2ee510d9'",
  "stackTrace": "   at ArtifactDeployer.Checker.Implementations.AzureBlobStorageArtifactChecker.GetArtifactInfo(String artifactId, StorageInfo storageInfo, CancellationToken cancellationToken)\r\n   at ArtifactDeployer.Handler.Implementations.DeploymentHandlerEventingDecorator.<>c__DisplayClass5_0.<<RetrieveArtifactInfoAsync>b__0>d.MoveNext()\r\n--- End of stack trace from previous location ---\r\n   at ArtifactDeployer.Handler.Implementations.DeploymentHandlerEventingDecorator.CaptureExceptionAsync(ContextType contextType, Func`1 action)"
}

Anyone know what is causing this issue? Sometimes it does work after a retry.

What happens during these steps is that the ArtifactDeployer module fetches the blob information from the cloud. Failure to obtain this information indicates that the blob is missing or that the request timed out.
Since a retry fixes the issue, I believe that the agent is unable to fetch the information...

Is this something you can reproduce, or does it appear to be random?
