# VNC compute node with error in RPC version

Hello I am testing a prototype using openstack with 1 manage node and 2 compute nodes, when a virtual machine is created in one of those nodes the web vnc console works, but when it is created in the other, a message is displayed "console is currently unavailable. Please try again later". I am pretty sure the configuration in the nova.conf is correct since the other node works, so I looked in the nova-compute log for any problems and looks like a process is terminating with an exception:

['Traceback (most recent call last):\n', '  File "/opt
/stack/nova/nova/openstack/common/rpc/amqp.py", line 461, in _process_data\n    **arg
s)\n', '  File "/opt/stack/nova/nova/openstack/common/rpc/dispatcher.py", line 178, i
n dispatch\n    raise rpc_common.UnsupportedRpcVersion(version=version)\n', 'Unsuppor
tedRpcVersion: Specified RPC version, 3.2, not supported by this endpoint.\n']


I don't think there is really a problem with the RPC version is this a bug? Is there a way to fix it?
