I suspect that this is a typical problem with api services run behind a load balancer, which terminates SSL. Because the port number 9696 indicates that the problem is observed with connection to neutron, a good first check is to ensure you set [oslo_middleware] enable_proxy_headers_parsing = True in your neutron.conf . (If you face the same problem with nova API then check the same option in nova.conf ) On 8/28/25 4:01 AM, Chang Xue wrote:
Hello, we just migrated using new openstack CLI tools, and when using pagination for both Nova and Neutron, we noticed that they are returning http href link although they are expecting https, causing failure: ``` openstack port list Failure: Unable to establish connection to http://openstack....example.com:9696/v2.0/ports: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response')). Retrying in 0.5s.1 retries left Unable to establish connection to http://openstack.....example.com:9696/v2.0/ports: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response')) ``` Is this a bug in Nova/Neutron? I tried other services like Heat, Keystone, etc, and they either returning https href links or just take relative path without schema/host.
Thanks, Chang
