Server: Mouting Dropbox External Storage : Error configuring OAuth1

[Butanal]

Steps to reproduce

1. Install the latest nextcloud.
2. Enable external storage, try to mount Dropbox with OAuth1 (app key and secret)

Expected behaviour

Dropbox auth app opening, allowing mounting Dropbox.

Actual behaviour

Error configuring OAuth1
Fetching request tokens failed. Verify that your app key and secret are correct.

That's it, I'm never able to mount it.

Nextcloud log (data/nextcloud.log)

Provides no useful information whatsoever to help (I checked, when the error occurs the last edited date isn't changed).
Should I change to verbose log ?

Additional info

I see no server-related or Dropbox-related reason as to why this is not working. My server is connected to the internet, no firewall blocking this access, Dropbox dev app created exactly as described in docs. Only remark is that I have TOTP enabled on my Dropbox account, although it used to work perfectly in another nextcloud instance for me.

Yesterday i connected Dropbox to Nextcloud.
I have the same problem, but after i clicked "Apply for production" everything is okay.
Here you can check my configuration in Dropbox API http://i.imgur.com/ZtLMvhG.png

[Butanal]

All manual pages recommend against applying for production. Moreover, it should work without this. I tried anyways, but Dropbox refused because "I have not connected any app to my Dropbox account before" or something like that.

Any idea then ?

[nicosea]

I had the same problem when I try to connect right after having created the dropbox app. After 10 minutes it worked.

[wksantiago]

Nextcloud version: 12.0.0 (stable)
Got the problem:
Error configuring OAuth1
Fetching request tokens failed. Verify that your app key and secret are correct.

But Dropbox uses OAuth2

[wksantiago]

Still getting:
Error configuring OAuth1

Fetching request tokens failed. Verify that your app key and secret are correct.

[fonorobert]

Getting the same issue, fresh install of latest (12.0.0) Nextcloud on Ubuntu 16.04

I don't know much about OAuth but i suspect @wksantiago is right about the problem being Dropbox not using OAuth1

[fonorobert]

Seems like this was resolved in Owncloud: https://github.com/owncloud/core/issues/7863

[fonorobert]

I made it work so the issue isn't with Nextcloud. Two things I did: set the app in dropbox to be available to other users, not just me and (embarassingly) typed the secret manually instead of copying it.

[xXSTrikeXx]

Want to say that it won´t be up anymore with Oauth1:

https://blogs.dropbox.com/developers/2017/09/api-v1-shutdown-details/

So there should be a PR for the right error message and the new Oauth2 :D

[notjoe]

Anyone know if there are plans to implement OAUTH2 support in the near future?

[MorrisJobke]

Dropbox support was moved to a separate app, please report issues with this over there: https://github.com/icewind1991/files_external_dropbox

Please try this new app, because it uses updated libraries that support newer Dropbox APIs.

The app works with Nextcloud 12+

[mathiasconradt]

@MorrisJobke Do you know why this app is not listed in the app store? Did the author just not submit it? Would be helpful if it's in the app store, because we get some requests from users that/why Dropbox connection isn't working.

[MorrisJobke]

Correct - it was not published to the app store yet
