Description
The following flows that have the failed tag below are the broken flows. They do not connect successfully.
We see that the client syn messages are not acked by the server side.

We are in shared GW mode in a 2 cluster design. Running the latest OVN-K from downstream https://github.com/openshift/ovn-kubernetes .
This problem can be seen in OCP 4.13.
