Unable to Login into Dropbox on Trello


I just added Dropbox to Trello with the  "Add Power Ups" button. When I click on Dropbox, and then "Choose a file or folder," it takes me to the login window. When I click on "Sign In" nothing happens. I have also manually added Trello as a Connected App in my Dropbox account.

See attached screenshots.


I've already gone into my browser preferences and unchecked the "Prevent cross-site tracking option" as Trello suggested I do. This option wouldn't make sense as I'm trying to use the Trello desktop app. I actually can use Dropbox in Trello in my browser no problems. But I really need to have it in the Desktop app.

I've also already tried un-installing and re-installing Trello as well.

Hey, same problem here on Win10, impossible to connect DropBox from the app. This is a real problem in the flow-work and make the app unusable for me.

Hey Tim, Dropbox is having issues on our desktop app. I've explained more here:

Is there a fix currently or we just have to wait?

Alex Waite Atlassian Team Dec 22, 2021

Hey @Tim Kusel - it's the latter I'm afraid. Will have to see if after New Years Dropbox will finally accommodate our security changes. 

Okay. I was on the phone with Dropbox support earlier regarding this matter and they seemed unaware of what was causing this issue. I tried using the Dropbox power up with the Trello website on my browser and it seemed to work just fine. 


So it seems that it's just the Trello desktop app that's having issues integrating Dropbox

Hi @Tim Kusel - hmm, that's frustrating, I'm sorry they said that. We've referred various users with your issue to Dropbox, and we've had varying responses from Dropbox support, some have had engineers not aware of any problem, some have had engineers aware of the problem but saying Dropbox won't fix it, some acknowledging that Dropbox needs to make the fix, etc. 

We're aware the issue is only on desktop, not web, so I'd use web for the time being if you need to integrate with Dropbox.

We're working on this daily at Trello Support - we understand how frustrating it is and I don't like that our users are having to deal with this issue between two companies. 

A lot of our engineers are on leave over the holidays but I've escalated this thread to them so they're aware that Dropbox still haven't investigated/fixed the bug on their side. I can't guarantee any sort of ETA - but please know we are pushing for a fix as soon as possible.

@Alex Waite any updates on this problem?

Alex Waite Atlassian Team Jan 09, 2022

@Tim Kusel - Dropbox has said they'll work on the issue this quarter, they have no ETA for a fix. 

Ok thanks for getting back
