Get-CacheHost is showing the status of nodes as UNKNOWN and caching service getting crashed - eventlog shows TimeoutException connecting to cache nodes.

Question

After installing and configuring App fabric 1.1 and ran Get-CacheHost command to check the status of the nodes. Its showing the Status of the nodes as UNKNOWN.  Some time caching service is crashing with Timeout exception and socketException connecting
to cache nodes. Below is the exception from the even log.  When I see the debug log I could see timeout exceptions connecting to cache nodes. Here is the error in debug log. I appreciate your help on this. Thanks.

Seems like a firewall issue, have you set the firewall rule to ALLOW inbound traffic to AppFabric?
