I tried to add to exist cluster on Linux a node that runs on Windows,  
But i get errors that master detected and then left:

There is network between the nodes(used Telnet)  
I Configured the unicast between them properly.  
The fact that the client node on Windows and the others on Linux can cause it?  
Thanks
