Hi, We have installed openstack ussuri version from ubuntu universe repository. We have installed octavia 6.2.0 version. after creating loadbalancer , listener and pool all are offline. but the LB operation is working as expected. changing the pool member is also working. octavia is installed in compute node. 5555 is listening and allowed in iptables (iptables -I INPUT -i o-hm0 -p udp --dport 5555 -j ACCEPT). amphora to octavia-worker(172.16.0.2) is reachable. Any idea to troubleshoot this issue Please find the log from octavia-worker ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// 2021-10-25 18:15:13.482 1192307 WARNING octavia.amphorae.drivers.haproxy.rest_api_driver [req-806e5e6b-46b0-4a52-900f-7c2d22d4442d - 9a817a70161d45fd9f0b5fe2cad30f5c - - -] Could not connect to instance.
