After a recent windows update to a Server 1016 R2, my virtual guest machines (Windows 10) hosted on the server would only permit Windows 10 RDP sessions once. The fix is to restart the guest, however if the session is disrupted or logged off the second and additional attempts will not connect. Again restating the guest will permit one session.
I updated to Player 15.5 and then to 15.5 Pro and the issue is ongoing.
Thanks,
