Scheduled Azure backup stopped working

I had successfully working scheduled Azure backup tasks (3 days in a week), but after the mandatory update of Azure Backup agent to version 2.0.8719.0, it doesn’t work anymore. The task runs for several hours until the timeout.

On demand backup seem to be working OK, so the connection with Azure should be also working. Any idea how to make the scheduled tasks working again? I am using Sever 2012 Foundation and backup some data folders.

Thanks for help,

Jan.
