Hi, I defined an external flat network and the Instances' network functionality is OK but the neutron logs continusly on the file server.log: *2018-12-04 03:21:22.206 2218 WARNING neutron.pecan_wsgi.controllers.root [req-0ac40043-ec93-490d-8770-5f4c49a11ea6 539929ca1549436cb4c4171e037e8df7 0a26c316d0d143229f7420cf7fa35bdc - default default] No controller found for: floatingips - returning response code 404: PecanNotFound* 2018-12-04 03:21:22.208 2218 INFO neutron.pecan_wsgi.hooks.translation [req-0ac40043-ec93-490d-8770-5f4c49a11ea6 539929ca1549436cb4c4171e037e8df7 0a26c316d0d143229f7420cf7fa35bdc - default default] GET failed (client error): The resource could not be found. 2018-12-04 03:21:22.209 2218 INFO neutron.wsgi [req-0ac40043-ec93-490d-8770-5f4c49a11ea6 539929ca1549436cb4c4171e037e8df7 0a26c316d0d143229f7420cf7fa35bdc - default default] 192.168.0.31 "GET /v2.0/floatingips?fixed_ip_address=192.168.0.205&port_id=15251089-950a-4a4b-998b-e7412350b8bc HTTP/1.1" status: 404 len: 309 time: 0.0077560 2018-12-04 03:21:22.284 2218 INFO neutron.wsgi [req-1177939c-e304-439a-a6bf-1a3d216a2336 539929ca1549436cb4c4171e037e8df7 0a26c316d0d143229f7420cf7fa35bdc - default default] 192.168.0.31 "GET /v2.0/subnets?id=9771f7f2-12f8-46bd-aca3-f1d26e0b9768 HTTP/1.1" status: 200 len: 835 time: 0.0708778 2018-12-04 03:21:22.368 2218 INFO neutron.wsgi [req-12dce42d-f6a0-4deb-902d-c46d95621013 539929ca1549436cb4c4171e037e8df7 0a26c316d0d143229f7420cf7fa35bdc - default default] 192.168.0.31 "GET /v2.0/ports?network_id=a90d7d71-1ff4-4a98-b2b9-68adaea7d1c4&device_owner=network%3Adhcp HTTP/1.1" status: 200 len: 1085 time: 0.0782819 2018-12-04 03:21:22.569 2218 INFO neutron.wsgi [req-e73d9ad4-4e70-4fb6-91a5-9bd02c606284 539929ca1549436cb4c4171e037e8df7 0a26c316d0d143229f7420cf7fa35bdc - default default] 192.168.0.31 "GET /v2.0/networks/a90d7d71-1ff4-4a98-b2b9-68adaea7d1c4?fields=segments HTTP/1.1" status: 200 len: 212 time: 0.1933858 2018-12-04 03:21:22.751 2218 INFO neutron.wsgi [req-79921bc1-7f1a-4eee-aeca-3b660aab0522 539929ca1549436cb4c4171e037e8df7 0a26c316d0d143229f7420cf7fa35bdc - default default] 192.168.0.31 "GET /v2.0/networks/a90d7d71-1ff4-4a98-b2b9-68adaea7d1c4?fields=provider%3Aphysical_network&fields=provider%3Anetwork_type HTTP/1.1" status: 200 len: 281 time: 0.1775169 2018-12-04 03:21:34.957 2218 INFO neutron.wsgi [req-50877132-2c57-4220-9689-5c739d415aa8 539929ca1549436cb4c4171e037e8df7 0a26c316d0d143229f7420cf7fa35bdc - default default] 192.168.0.32 "GET /v2.0/ports?tenant_id=8cd6e51308894e119d2ad90ed15e71d2&device_id=882901a0-e518-4b4b-bf08-e998c4c0c875 HTTP/1.1" status: 200 len: 1094 time: 0.1096959 2018-12-04 03:21:35.116 2218 INFO neutron.wsgi [req-0305018f-b085-46c2-86cd-1769432cda91 539929ca1549436cb4c4171e037e8df7 0a26c316d0d143229f7420cf7fa35bdc - default default] 192.168.0.32 "GET /v2.0/networks?id=a90d7d71-1ff4-4a98-b2b9-68adaea7d1c4 HTTP/1.1" status: 200 len: 877 time: 0.1516771 I checked the neutron.conf and there was not any web_framework attribute under the [Default] section.

From OpenStack forum, someone suggest to set *web_framework = legacy *in neutron.conf. I did but it had no effect and neutron still is logging the so-called warning.

Is this a bug or I miss something in configuration? I use the OpenStack Rocky.
