Hello everyone! I've installed OpenStack Ussuri on my home servers (one controller and one compute node, both running OpenSuse Leap 15.3) based on the instructions in the docs(https://docs.openstack.org/install-guide/openstack-services.html#minimal-dep...) Everything works until I launch an instance in Horizon. The instance gets stuck on "Scheduling". Looking trough the logs I've came across nova-conductor.log(on the controller), which contained the following error log(full log in the attachments): 2022-07-08 00:48:08.846 25886 ERROR oslo_messaging.rpc.server [req-eb225ffd-9b12-4e80-987b-34f0317082c6 741cb0b6280cb6fbedf1d8c6df4fc854b3e177e331441e019b961839089154d6 9b41f3e228984401a7642f94cd47dc73 - 4596c7f3b97740b3adfa8f82b6240654 4596c7f3b97740b3adfa8f82b6240654] Exception during message handling: amqp.exceptions.AccessRefused: (0, 0): (403) ACCESS_REFUSED - Login was refused using authentication mechanism AMQPLAIN. For details see the broker logfile. I'm 100% sure my RabbitMQ username and password are set correctly in nova.conf. I've included my nova.conf too, with the passwords removed. I would be really thankful, if someone could point me in the right direction! P.S: Please excuse me for any grammatical or spelling mistakes, English is not my first language.
