I deployed a Nextcloud Docker image on Fedora (uname -a outputs: ‘Linux localhost.localdomain 6.8.7-300.fc40.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Apr 17 19:21:08 UTC 2024 x86_64 GNU/Linux’). Initially, it worked well with the storage path ‘/mnt/nextcloud_storage’. However, after changing the mount structure to ‘/mnt/storages/nextcloud_storage’, the Nextcloud web control panel shows the error:
“Your data directory is not writable. Permissions can usually be fixed by giving the web server write access to the root directory. See https://docs.nextcloud.com/server/20/go.php?to=admin-dir_permissions.”
Below are some relevant details:

I have verified that the permissions on the new directory are set to allow read/write access, and I truned the SELinux off, but I am still encountering the issue. Can anyone suggest what might be wrong or how to troubleshoot this further?
Thank you in advance for your help!
What I have tried:
Changed Ownership and Permissions:
sudo chown root:root /mnt/storages/nextcloud_storage
sudo chmod 755 /mnt/storages/nextcloud_storage
Did not work.
Applied SELinux Context:
sudo chcon -Rt svirt_sandbox_file_t /mnt/storages/nextcloud_storage
Did not work.
Manual File Creation Inside Docker:
- Entered the Docker container and successfully created a file in the /var/www/html/data directory.
root@039703cb2894:/var/www/html/data# ls
YeYuXueSheng ZhangYujie appdata_ocwqmnttf9hg fengyuwuzu211 files_external images index.html nancunchild naoh nextcloud.log xie zhiyu
root@039703cb2894:/var/www/html/data# echo write > ./writable_test
root@039703cb2894:/var/www/html/data# ls
YeYuXueSheng ZhangYujie appdata_ocwqmnttf9hg fengyuwuzu211 files_external images index.html nancunchild naoh nextcloud.log writable_test xie zhiyu
root@039703cb2894:/var/www/html/data# cat writable_test
write
And there is something shouled be pay attention: there is no www-data user in my machine, it only exists in docker.
