[v6.4.0] Master node does not send cached data to mirror node

I have simple 2 nodes topology: master node - mirror node(ip addr: 192.168.77.12).
Servers can access each other on default port 8126.

My config yml:

Code (CSharp):

1.  
2. Cache:
3.   defaultModule: cache_fs
4.   options:
5.    processor:
6.      putWhitelist: []
7.    cache_ram:

9.      pageSize: 100000000
10.      maxPageCount: 100
11.      minFreeBlockSize: 1024
12.      persistence: true
13.      persistenceOptions:

33.      highReliabilityOptions:
34.        reliabilityThreshold: 2
35.        saveUnreliableVersionArtifacts: true
36.        multiClient: false
37. Mirror:
38.   addresses: [192.168.77.12]
39.   options:
40.    queueProcessDelay: 2000
41.    connectionIdleTimeout: 10000
42. Server:
43.   port: 8126
44.   options:
45.    allowIpv6: false

During the unity-cache-server startup on master node i see the following entries in log:

Code (CSharp):

1.  
2. unity-cache-server ucs[27713]: [Cluster:M] [TransactionMirror] Mirroring transactions to 192.168.77.12:8126
3. unity-cache-server ucs[27713]: [Cluster:1] [TransactionMirror] Connecting to 192.168.77.12:8126
4.  

On my mirror node, using tcpdump i can see that the master node is sending initial handshake.
The problem is:
When unity sends data to the master node cache the data reflects on master node only and doesnt sending on mirror node.
I have also tried to start unity-cache-server service on master node like this:

Code (CSharp):

1.  
2. node /usr/bin/unity-cache-server --workers 1 --mirror 192.168.77.12:8126  --cache-module cache_fs --NODE_CONFIG_DIR=/etc/unity-cache-server
3.  

After it started up i can see this process in process tree with --mirror 192.168.77.12:8126 option , but the cached data doesnt reflects on mirror node either.
