centos9 wallaby scenario 10 fails octavia tempest test_traffic_ops

At [1][2][3][4] the periodic-tripleo-ci-centos-9-scenario010-ovn-provider-standalone-wallaby and periodic-tripleo-ci-centos-9-scenario010-kvm-standalone-wallaby are failing during tempest run and specifically

octavia_tempest_plugin.tests.scenario.v2.test_traffic_ops

Trace looks like:

ft2.1: setUpClass (octavia_tempest_plugin.tests.scenario.v2.test_traffic_ops.TrafficOperationsScenarioTest)testtools.testresult.real._StringException: Traceback (most recent call last):
  File "/usr/lib/python3.9/site-packages/tempest/lib/common/ssh.py", line 131, in _get_ssh_connection
    ssh.connect(self.host, port=self.port, username=self.username,
  File "/usr/lib/python3.9/site-packages/paramiko/client.py", line 349, in connect
    retry_on_signal(lambda: sock.connect(addr))

  File "/usr/lib/python3.9/site-packages/paramiko/client.py", line 349, in <lambda>
    retry_on_signal(lambda: sock.connect(addr))
socket.timeout: timed out

This appears to be inconsistent because looking at the build history at [5][6] there are some SUCCESS as well as FAILURE. However this issue is ongoing for a few days - earliest example I could find is from the 06th (logs at [4])
