I can't add an external storage despite using an admin account

I can’t add an external storage device with my admin account. It only shows “There is no external storage set up, or you do not have permission to do this.”

@Jannis,

Did you read and implement the documentation for adding and configuring external storage first?

https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/external_storage_configuration_gui.html

If so which external storage have you configured / allowed under the ‘Administration’ heading?
