Cannot connect via RDP

Cannot connect via RDP


I'm having a Problem to connect to Windows Machines via Remote Desktop.
All I can see is a Pop-Up "Please wait while connecting", but it
instantly closes.

The Password Manager logs don't tell much except "serverout0.txt":

[10:45:47:196]|[11-17-2016]|[com.toremote.ah]|[WARNING]|[80]: Unknown client was closed! Reason: No header from:<My-Computer IP>|

PMPAgent on the Target Machine is running. I can connect directly via
RDP from my Computer. Firewalls are stopped. Connections via SSH work fine.

Any Ideas? Thanks in Advance!
