Hello, I try to install Octavia and i'm facing an issue with octavia-health- manager-listen-port interface. I use Openstack Ussuri on Ubuntu 18.04 with linuxbridge plugin I followed this procedure: https://docs.openstack.org/octavia/latest/install/install-ubuntu.html#instal... When I try to create my loadbalancer I got this error: WARNING octavia.amphorae.drivers.haproxy.rest_api_driver [-] Could not connect to instance. Retrying.: requests.exceptions.ConnectionError: HTTPSConnectionPool(host='10.244.3.243', port=9443): Max retries exceeded with url: // (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x7fe1ec077080>: Failed to establish a new connection: [Errno 113] No route to host',)) From my interface "o-hm0" I cannot ping 10.244.3.243 but if I try to ping from DHCP namespace it works fine. I think the problem is my "octavia-health-manager-listen-port" port appears "DOWN" when I list every ports. I figured out than Neutron didnt update iptables rules, probably because the interface is DOWN but if I add these rules: iptables -A neutron-linuxbri-FORWARD -m physdev --physdev-out o-bhm0 -- physdev-is-bridged -m comment --comment "Accept all packets when port is trusted." -j ACCEPT iptables -A neutron-linuxbri-FORWARD -m physdev --physdev-in o-bhm0 -- physdev-is-bridged -m comment --comment "Accept all packets when port is trusted." -j ACCEPT Amphora is able to communication with health manager port then the loadbalancer becomes UP but now I got this WARNING: 2021-01-21 15:27:21.230 2999834 WARNING octavia.amphorae.drivers.health.heartbeat_udp [-] Health Manager experienced an exception processing a heartbeat message from ('10.244.3.243', 30684). Ignoring this packet. Exception: 'NoneType' object has no attribute 'encode' I guess it's all about the port being stuck in DOWN state. Do you have any input how to configure this port?
