Persistent timeout

The following lines of code seem to constantly lead to a timeout exception and I'm not sure why? Note timeout set to 10s. The error is a "System.Threading.Tasks.TaskCanceledException' - 'The request was canceled due to the configured HttpClient.Timeout of 5 seconds elapsing"

Thanks
