Pod can't connect to another POD on same node


I got 2 pod with ip: A) and B) on node with IP:

Pod A can ping node host and also node host can ping pod b. but pod a can’t connect to pod b.

Any idea? Thanks a lot.

What version of Calico? how did you install? What version of k8s and how was it installed? Do you have any network policy in place?
