Flower: Flower 0.9.5 404 error

Created on 3 Aug 2020 · 4Comments · Source: mher/flower

Describe the bug
I'm using the Docker hub image at mher/flower.

This is from my docker-compose.yaml

  flower:
    image: mher/flower:0.9.5
    depends_on:
      - broker
    env_file:
      - worker/.env
      - flower/.env

I previously had Flower working in version 0.9.2 but when I upgraded to 0.9.5 I now get a "404: Not Found" whenever a load the home page (http://flower:5555). I am asked to authenticate using basic authentication, but then a 404 error is presented.

To Reproduce
$ docker-compose build --pull
$ docker-compose up -d

Then I open the page in the web browser or use the curl command.

Expected behavior
I expect to see the normal Flower home page (or API at /api/)

Screenshots

$ docker-compose exec --user my_user app curl http://flower:5555
<html><title>404: Not Found</title><body>404: Not Found</body></html>

$ docker-compose logs flower

Also having the same issue, I'm using flower in a Docker container also running nginx to http-proxy to it.
Flower is too useful to me, I have waited to upgrade Celery because of the other bug on 5.0, wish I had time to contribute!

I solved this by downgrading to version 0.9.4

This is from the new docker-compose.yaml:

  # Celery task monitor
  flower:
    image: mher/flower:0.9.4
    depends_on:
      - broker
    env_file:
      - worker/.env
      - flower/.env

And then I changed the container environement:

$ git pull && docker-compose build --pull flower && docker-compose up -d
Already up-to-date.
flower uses an image, skipping

I'm having the same 404 issue, not via docker but from a straight installation of flower 0.9.5 (no docker).

Similarly to @Joe-Heffer-Shef the problem is "solved" by downgrading flower to 0.9.4.
