We cannot reproduce the issue with the same qemu version on RHEL 7 host.
Do you see that the file is starting to copy (do you see any progress in Windows GUI)?
What is the status of network connection before you copy? In the first screenshot network icon has a yellow exclamation mark (usually it means that the NIC didn't get IP address).
Is there any problem with network after the connection failed?
If you ran ping during the copy - what do you see?

Make sure the guest could obtain ip before starting copying.
