I have just completed barebones installation but am receiving errors from the API when I try to add/edit anything in the UI. It is not an issue with the wss port it is [https://taiga.mydomain.com/api/v1/](https://taiga.mydomain.com/api/v1/) I can receive successful responses back from the api directly so it seems that it is not an issue with the nginx proxy. When I monitor the output of “docker logs taiga-docker\_taiga-back\_1” I receive this: ```auto amqp.exceptions.AccessRefused: (0, 0): (403) ACCESS_REFUSED - Login was refused using authentication mechanism AMQPLAIN.

Hi @jasonbdn It seems that the backend, when it is going to send the asynchronous task that generates the new entry in the timeline, cannot connect to rabbitmq. ```auto File "/taiga-back/taiga/timeline/signals.py", line 28, in connection.on_commit(lambda: push_to_timelines.delay(project_id, ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ (...) File "/opt/venv/lib/python3.11/site-packages/celery/app/base.py", line 788, in send_task amqp.send_task_message(P, name, message, **options) (...) File "/opt/venv/lib/python3.11/site-packages/amqp/connection.py", line 667, in _on_close raise error_for_code(reply_code, reply_text, amqp.exceptions.AccessRefused: (0, 0): (403) ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile. ``` The error message is ```auto (403) ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile. ``` Check your settings value for `CELERY_BROKER_URL` (and `EVENTS_PUSH_BACKEND_OPTIONS ` could be wrong too). And you can review the log files of rabbitmq too to get more info about the cause of the error during the authentication. Best regards ---

Remove the containers of rabbitmq and relauch the docker compose again.
