Remote not working with wireless connection

I am running Openelec on Raspberry PI. I am able to connect to Kodi using the official application when I connect the PI to network via patch cable. However if I use Wi-Fi to connect to my network I am not able to connect to it using the application.
When connected with patch cable the host is auto detected in Kore application and I am able to connect.
When connected to network using WiFi the kore remote application doesn’t show any host neither does it work when I enter the IP manually. I am getting the IP from DHCP server, double checked username and password.
