Issue in connecting to mysql pod from grafana pod in K8s


I have deployed the Grafana on Kubernetes cluster and I dont want to use the default database i.e. sqllite. So I deployed one more deployment for Mysql with mysql ClusterIP service (mysqlsvc) i.e. service to connect to mysql database within cluster with other applications like wordpress.
I have set the environment variables like GF_DATBASE_HOST=mysqlsvc.
Grafana is unable to connect to my mysql service as it is unable to find it.

Is this normal or is there any specific way to connect grafana pod with mysql pod.
