I am running Aerospike C# demo application on my local machine. for this I done following steps

1. Installed VirtualBox
2. After that I installed Vargent
3. Configured Everything , Its working now !

$ vagrant ssh -c “sudo service aerospike status” \*\*\*\*\*\*\*\*\*\*Aerospike Database Server is running! \*\*\*\*\*\*\*\*\*\*Aerospike Monitoring Console is running! asd (pid 1285) is running… Connection to 127.0.0.1 closed.

Also its showing in web client.

But when I trying to connect from C# Demo application it not connecting

I am using these settings

**Server - 192.168.1.8 (IP address of my local machine)**  
**Port - 3000**** User - admin ****Password-**

Not putting password its empty .

**Error Message -** Error code 51 :Authentication Failed
