k8s-bigip-ctlr cannot get list of nodes

Hello. I'm trying to apply BIG-IP to my kubernetes cluster with cluster mode. My kubernetes cluster uses Calico BGP for network fabric, and BIG-IP license is okay.

I created secret(including BIG-IP credential), configmap containing virtual server, and RBAC, then deploy k8s-bigip-ctlr.

The pod seems to work fine, but when I check logs, there is an error that is '[WARNING] Unable to get list of nodes, err=Get https://10.233.0.1:443/api/v1/nodes: dial tcp 10.233.0.1:443: i/o timeout'. No other pods have such error log, so I have no idea how can I solve this. Does anyone help me? Versions of each are below.

BIG-IP: 13.1.0

Calico: 3.7

kubernetes: v1.13.4

k8s-bigip-ctlr: 1.9.0
