  <p>I am using latest version of StackExchange.Redis, I also tried by downgrading version as suggested in couple of articles but no luck, I am also setting <strong>AbortOnConnectFail</strong> as false. Redis server is up and working fine, I can do telnet and also can see all keys through a tool(Redis React)</p>
  
  <p>Strange things is that, same code is working fine when using in a website with same Redis server.</p>
  
  <p>Please guide. Thanks</p>
