Impossible to delete custom icon for external website due to nginx rejecting DELETE requests

[milouse]

Describe the bug

When trying to delete a custom icon from the "external website" app (in https://nextcloud_install/settings/admin/external), nothing happen. The icon is note deleted and no error message is displayed. Looking at the developers tools of the browser show that clicking on the trash icon leads to a DELETE XHR requests, which fail as nginx does not seem to accept such requests.

Context

• Hardware: VPS bought online
• YunoHost version: 11.1.20
• I have access to my server: Through SSH
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no. Nextcloud is installed as a subdirectory of the main domain, not on its own domain.
• Using, or trying to install package version/branch: N/A
• If upgrading, current package version: N/A

Steps to reproduce

• Activate the external websites application
• Upload a new custom icon for it in the external websites app settings
• Click on the trash icon next to the new icon.
• … nothing happen

Expected behavior

The icon is removed

I confirm this bug is still here at this date.

Workaround: it's possible to delete the icons in the path (i don't remember where exactly)
