Error while creating IpamDriver plugin

I am creating a v2 Ipam Plugin. I created the rootfs and created , enabled the plugin. However I am getting error

May 16 17:35:53 ishant dockerd[18480]: time=“2017-05-16T17:35:53.175424780+05:30” level=warning msg=“Unable to connect to plugin: /run/docker/plugins/a36e89e0b9492e9bd59bedd18906a89fa49b3cee235e5ec0c074882812471fc3/infoblox.sock/IpamDriver.GetCapabilities: Post http://%2Frun%2Fdocker%2Fplugins%2Fa36e89e0b9492e9bd59bedd18906a89fa49b3cee235e5ec0c074882812471fc3%2Finfoblox.sock/IpamDriver.GetCapabilities: dial unix /run/docker/plugins/a36e89e0b9492e9bd59bedd18906a89fa49b3cee235e5ec0c074882812471fc3/infoblox.sock: connect: no such file or directory, retrying in 1s”

I can see that the socket file exists in the path

root@ishant:/run/docker/plugins# ls -l /run/docker/plugins/a36e89e0b9492e9bd59bedd18906a89fa49b3cee235e5ec0c074882812471fc3/infoblox.sock

Any suggestion on where I am going wrong
