HA kubernetes master setup using bigip

I am trying to setup a HA kubernetes cluster with 3 master node using Bigip. I have setup the VIPS added the wild card cert and server profile. I created an associate pool with all three master node ip and port. I followed this doc: to step as per their instruction. I am getting error below error during cluster bootstrapping. Do we need to manually upload any certificate to bigip to make it work? Kindly help. Thank you!
