Hi Shelly,

Thanks for your answer. Your version of GuestAgent is too old. The latest
version is 103.0.0.
Version 100.0.0 has a bug related to wrong error messages. When you try to
freeze FS, GA can return an error that the GA is not available.

Please try again with the latest version. I think it should work fine. If
you still will have problems, will try to debug them.

Best Regards,
Konstantin Kostiuk.
