No connectivity between sites L3 in one VM

We have a 1 node setup (non-cluster) with Openstack (RedHat - 9 ) with 2 computes.

vpn-interface (1.1.1.38, 8dc04953-fa4e-4c12-b2ac-7f27148050c7) (add dump models):
{

"netvirt-plugin-common:generation-number": 2,
"netvirt-plugin-common:shadow": true,
"netvirt-plugin-common:remote-ip": "10.80.2.11",

],
"vpn-instance-name": "893814b1-44ef-4fdd-8b60-8adf8f8f704c",

},

It was unable to install the flow on one of the computes (the flow was installed on the other compute)

We see in the ODL log the following error :
