API Not Working With Solid Explorer or Root Explorer.

The API isn't working on Solid Explore or Root Explorer. I login successfully but the apps won't pick up the account. Was working until this morning.

You should contact the developers of those apps. They integrated Dropbox into their applications, so they would be the ones that need to support that connection. Dropbox won't have any insight into those applications. It's up to the developers to support the apps.

This definitely appears to be something with the app. I installed Solid Explorer and attempted to link it to my Dropbox account. The authorization process works because the app now appears in the list of connected apps in my account as seen below. You can verify this as well on this page in your account.

However, the process never completes within the app. I'm just returned to the login screen with no error or message. The Dropbox API is likely responding, but a problem with the app is preventing the process from completing the link.

The developers of the app will be the best people to resolve this. They can look at the response from the Dropbox API and figure out what the issue is. It's likely that they'll need to update their app, especially if something has changed in the API.

Yes.  I've done that.  It just broke on both today though.  I can't see two apps failing, unless Dropbox changed something today and they need to update their apps.

Solid Explorer and Wardencam stopped working for me yesterday, for the third time (the second time was on January 15, 2026).

This is infuriating. Maybe it's time to move somewhere else. Any suggestions for 2-3 TB cloud services? 

And yes, I read that the developers need to update. You could have kept these apps working and given them more time to update?

Hi hölökynkölökyn​ 

I understand how frustrating this is.

The issues encountered with these apps may be related to a new certificate rollout.

In this case, these apps stopped working because the third-party developer didn't update their integration/SDK to remain compatible with the platform changes. We provided advance notice for changes like this to give developers time to prepare and make any necessary updates. Specifically, updates for this change were communicated on:

• June 26th, 2024 via email
• June 26th, 2024 via blog post
• February 19th, 2025 via email
• October 1st, 2025 via email

Because we don't own or control that third-party app's code or release process, we aren't able to keep it working on their behalf once an update is required. 

Thank you.  Thing is, was there a cut off date?  These apps were working until January 20th, 2026.

UPDATE.  Problem has stopped.   Both Solid Explorer and Root Explorer are working.

It WAS YOU DROPBOX, and you passed the buck.

No updates to the apps either.  🐂 💩

The rollout is being done in phases, with brief validation periods before the change is finalized, which is why this "issue" may appear resolved temporarily or why it may have appeared to be working before January 20th.
