Amazon is trying to connect elastiCache cluster endpoint using memac-client but error is taking place

  Memkach :: Memack ash: no connection to the server (testcachecluster.u098ed.cfg.us e1.cache.amazonaws.com:11211 DEAD (timeout :: error: execution expired C) / Program Data / Rail Installer / Ruby 1.9.3 / Lib / Ruby / Games / 1.9.1 / Games / Mac-Mac-Client-1.8 5 / Lib / memcache.rb: 863: In `with_socket_management 'with C: / Programmate / RailsInstaller / Ruby1.9.3 / lib / ruby ​​/ gems / 1.9.1 / gems / me mcache- client- 1.8.5 / lib / memcache.

 Okay, for me, the problem was a security group. You only exclude the exhaust nodes Can access examples, which have a security group, which are listed in the Security Group.  
 For me, in my ec2 example there is a security group of "web". In ElasticShow, I added "Web" to the "Default" Loostatic Safety Group.

 Also, try to use any of these two gems:  
  
  
 I am using later and it works great because it uses the nodes autodivir.
