Exception: Creating storage failed

[voodoomatz]

Hi,
I added the app successfully and activated in admin>settings for all users.
I set up a Dropbox app. In user>settings>external storage, I selected DropboxV2, entered client id and client secret and successfully granted access. However, I still receive the following error:

Exception: Creating \OCA\Files_external_dropbox\Storage\Dropbox storage failed

The Nextcloud error log shows:

files_external | Exception: Creating \OCA\Files_external_dropbox\Storage\Dropbox storage failed/share/CE_CACHEDEV1_DATA/Web/nextcloud/apps/files_external/lib/config.php - line 237: OCA\Files_external_dropbox\Storage\Dropbox->construct({ configured ...

System:
Apache 2.3, PHP7.2, Nextcloud 14.0.1

Any ideas?

I'm experiencing something very similar on NextCloud 13. The indicator doesn't turn green after granting access, and I get "Exception: Creating \OCA\Files_external_dropbox\Storage\Dropbox storage failed." in the Files view.

Same here:

• NextCloud version: 14.0.1.1
• files_external_dropbox: 1.0.0
• PHP 7.0.30-0+deb9u1
• Apache/2.4.25

Same here

Nextcloud 14.0.3

Encountered the same issue, working with NextCloud's docker container v14.0.3.0.

Has anyone managed to get this working?

Has anyone managed to get this working?

I ended up creating a dropbox docker container with a mounting point on the host that is defined as external storage within nextcloud, works great so far.
