There is no l3 agent hosting this router and since it has HA disabled it did not failover to any other node.

[root@neen.platform9.net chinmay(admin)]# neutron l3-agent-list-hosting-router 3d3ec419-e0e5-45fa-a661-bfeb14261658
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

[root@neen.platform9.net chinmay(admin)]#
To correct this, added the router to another L3 agent.
[root@neen.platform9.net chinmay(admin)]# openstack network agent list | grep l3
