Network connectivity alternative Workstation

I installed a Windows Workstation and configured my Gateway to use my torconfig.
Now my problem is, that after a while, about one hour the networkconnectivity suddenly ends.
How can i locate the error?
Here is a Picture of what whonix arm shows after the connection ended.

Most messages by ARM are irrelevant. If you want to learn about what they mean, see:

Looks like sdwdate broke connectivity by messing up your clock. It’s a known bug (https://github.com/Whonix/Whonix/issues/295) and will be fixed in Whonix 9. When using VM’s the easiest way would be to power off, and power on the VM again.
