Pod can't connect to another POD on same node

hi,

I got 2 pod with ip: 10.122.153.94(Pod A) and 10.122.153.93(Pod B) on node with IP: 172.18.86.176

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?
