[Nextcloud] Failed to call imaginary

[janusn]

I have been using imaginary for Nextcloud preview for years. Recently after a couple migrations and several server upgrade, I have found that Nextcloud does not call imaginary for preview.

I installed Nextcloud and imaginary via docker. I am certain that the Nextcloud user abc in the container can call imaginary and imaginary logs the calls as show below:

# docker exec -it -u 3008:5004 nextcloud bash
bash: /root/.bashrc: Permission denied
abc@cef674d6be6a:/$ id
uid=3008(abc) gid=5004(abc) groups=5004(abc)
abc@cef674d6be6a:/$ cd /mnt/logs
$ curl -O "http://imaginary:9000/crop?width=500&height=400&url=https://raw.githubusercontent.com/h2non/imaginary/master/testdata/large.jpg"
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 38616  100 38616    0     0  51212      0 --:--:-- --:--:-- --:--:-- 51214

And the container log of imaginary shows:

Imaginary has started
172.47.0.5 - - [06/Jul/2024 18:37:20] "GET /crop?width=500&height=400&url=https://raw.githubusercontent.com/h2non/imaginary/master/testdata/large.jpg HTTP/1.1" 200 38616 0.7436

However, when I opened folders with images on Nextcloud, no sign of imaginary being called.

Here is my compose.yaml:
