Unable to connect to libvirt qemu+ssh [duplicate]

First I installed KVM and Qemu on local machine to do some testing. Now I wanted to do so on a remote productive system. I can connect to the productive system from my laptop but not from local machine to remote productive system. The error message is:

Unable to connect to libvirt qemu+ssh://UserName@IpOfServer:Port/system.
Cannot recv data: Der Wert ist zu groß für den definierten Datentyp
Verify that the 'libvirtd' daemon is running on the remote host.
Libvirt URI is: qemu+ssh://UserName@IpOfServer:Port/system
Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/connection.py", line 1036, in _do_open self._backend.open(self._do_creds_password) File "/usr/share/virt-manager/virtinst/connection.py", line 144, in open open_flags) File "/usr/lib/python2.7/dist-packages/libvirt.py", line 105, in openAuth if ret is None:raise libvirtError('virConnectOpenAuth() failed')
libvirtError: Cannot recv data: Der Wert ist zu groß für den definierten Datentyp

I can login from local system via ssh to remote system,

libvirt-bin libvirt-clients libvirt-daemon libvirt-daemon-system

is installed and my user is added to libvirt group but I can't get it to work.

It is the same error like here: Unable to connect to libvirt

I didn't see the correlation between the two different errors.
