[rabbitmq-discuss] Clustering problem

[0x49D1]

Hello,
i have a problem when trying to create rabbitmq cluster on windows.
Servers are r1 and r2. r1 can ping r2, r2-r1.
I did all, mentioned in instruction http://www.rabbitmq.com/clustering.html#creating
but get such message:
Clustering node rabbit at R2 with [rabbit at R1] ...
Error: {no_running_cluster_nodes,[rabbit at R1],[rabbit at R1]}

When i try to see status of r2 from r1 i see such message:
C:\Program Files (x86)\RabbitMQ Server
\rabbitmq_server-2.7.0\sbin>rabbitmqctl -n
 rabbit at r2 status
Status of node rabbit at r2 ...
Error: unable to connect to node rabbit at r2: nodedown
diagnostics:
- nodes and their ports on r2: [{rabbit,49214}]
- current node: rabbitmqctl12518 at r1
- current node home dir: C:\Users\Administrator
- current node cookie hash: QsJXNAJ4kikETB6oLkVJbw==
sane on r1-r1:
C:\Program Files (x86)\RabbitMQ Server
\rabbitmq_server-2.7.0\sbin>rabbitmqctl -n
 rabbit at r1 status
Status of node rabbit at r1 ...
Error: unable to connect to node rabbit at r1: nodedown
diagnostics:
- nodes and their ports on r1: [{rabbit,49355},
{rabbitmqctl2810,49624}]
- current node: rabbitmqctl2810 at r1
- current node home dir: C:\Users\Administrator
- current node cookie hash: QsJXNAJ4kikETB6oLkVJbw==

Tho firewalls are off on both servers. r2 is in r1's hosts. Dont know
where the problem is and cant find any solutions on discussion or
troubleshooting.
