Hi, Controllers nodes must be able to connect with amphora to make healthchecks. Since the logs are shown "no route to host error", have you tried to configure a route to octavia management network gateway? Regards. On Mon, Apr 7, 2025, 11:54 Thamanna Farhath <thamanna.f@zybisys.com> wrote:

Hi OpenStack Community,

I am currently facing an issue with the Load Balancer (Octavia) service in my OpenStack deployment and would appreciate your guidance or suggestions on how to troubleshoot and resolve it. ------------------------------ *Environment Details:*

-

*OpenStack Version:* 2023.1 (Antelope) -

*Operating System:* Ubuntu 22.04 -

*Octavia Backend:* Amphora -

*Network Type:* VXLAN -

*Deployment Tool:* Kolla Ansible

------------------------------ *Issue Summary:*

After creating a Load Balancer, the Amphora instance is successfully launched. However, approximately *18 minutes later*, the Load Balancer transitions to an *ERROR* state.

*Error Observed:*

octavia.common.exceptions.ComputeWaitTimeoutException: Waiting for compute id a222527f-8336-4fb1-8e9e-0e3ac6e8d580 to go active timeout. octavia.amphorae.driver_exceptions.exceptions.AmpConnectionRetry: Could not connect to amphora, exception caught: HTTPSConnectionPool(host='192.168.200.247', port=9443): Max retries exceeded with url: // (Caused by NewConnectionError: Failed to establish a new connection: [Errno 113] No route to host)

------------------------------ *What I’ve Tried:*

1.

Created a VXLAN-based internal network:

openstack subnet create --network octavia-mgmt-net --subnet-range 192.168.200.0/24 octavia-mgmt-subnet openstack router create octavia-router openstack router add subnet octavia-router octavia-mgmt-subnet openstack router set octavia-router --external-gateway <public-network-id>

2.

Manually configured OVS interface:

ovs-vsctl add-port br-int octavia-mgmt -- set interface octavia-mgmt type=internal ip addr add 192.168.200.1/24 dev octavia-mgmt ip link set octavia-mgmt up

3.

Security groups are open (allowing all ingress and egress). 4.

Verified OVS bridge setup – interface appears correctly on br-int.

------------------------------ *Behavior Noticed:*

-

Amphora instance gets created but fails to communicate with the controller after a while,so health checks fails. -

The controller cannot reach the Amphora management IP (192.168.200.x). -

Logs show heartbeat/connection issues (No route to host, timeouts).

------------------------------ *Request for Help:*

I would appreciate any of the following:

-

Suggestions to verify if the management network is properly routed from controller to Amphora. -

Best practices for setting up the Octavia management network using VXLAN. -

Troubleshooting steps for verifying health manager connectivity to Amphora.
