GCE Server group Unhealthy after deploy


I am using Spinnaker since long but recently tried using it for GCE(Was using for GKE previously). Now when I am creating a new server group it is not becoming healthy. I am using TCP type health check (Setting up for Zookeeper to start with). I logged into the created node and checked that the port is up and listening. Even through LB.

Not sure what am I doing wrong.


Ok, Found the RCA myself. Basically I did not allow the list of probe servers of GCP. Created a rule for allowing the probe servers and everything worked after that.
