Question details
The user is unable to link their Dropbox account to Adobe Reader on a tablet, repeatedly encountering a connection error.

- Product
- Adobe Reader
- Device & OS
- Tablet
- Scenario
- Attempting to connect a Dropbox cloud storage account to Adobe Reader in order to access and edit PDF files stored in the cloud.
- Observed behavior
- After accepting the Dropbox API request, the app displays the error message 'Dropbox account could not be linked. Please try again later.' Reinstalling, restarting, changing passwords, and switching networks do not resolve the issue.
Ensure your tablet is connected to a stable internet network and verify that your device is not currently running in a strict battery-saver or data-saver mode.
Enable Background Data Usage for Adobe Reader
Adobe Reader requires background internet access to complete the Dropbox account connection and verify the API request.
When a tablet restricts background data, applications are prevented from using the internet unless they are actively open on the screen. Because the Dropbox linking process often switches between apps or browsers to authenticate, restricting background data interrupts the handshake, resulting in a linking failure.
Navigate to the main Settings app on your tablet and tap on 'Network & Internet' or 'Apps', depending on your device's operating system.
Find and select 'Adobe Reader' from your list of installed applications to view its specific app info and permissions.
Tap on 'Mobile data & Wi-Fi' or 'Data usage'. Ensure that the toggle for 'Background data' is turned on so the app can communicate with Dropbox servers in the background.
Relaunch Adobe Reader and attempt to link your Dropbox account again. The connection should now authenticate successfully.

Perform a Clean Reinstallation Using the Cleaner Tool
Corrupted app data or lingering registry files might block the API connection, requiring a clean uninstallation before reinstalling.
Access Dropbox PDFs Seamlessly with WPS Office
If Adobe Reader continues to struggle with cloud connections, switch to WPS Office. It is a lightweight, reliable alternative that effortlessly integrates with Dropbox, allowing you to open, edit, and save PDFs and Office documents directly from the cloud without connection glitches.
- 1. Install WPS Office: Download and install WPS Office for free from your tablet's official app store.
- 2. Access the Cloud Menu: Launch WPS Office and navigate to the 'Open' tab, then select the 'Cloud' or 'Add Cloud Storage' option.
- 3. Link Your Dropbox: Choose Dropbox from the list of providers, log in with your credentials, and instantly access your cloud files.

Frequently Asked Questions
Why do I get a 'Dropbox account could not be linked' error in Adobe Reader?
This usually happens when your tablet's background data is restricted. The app loses internet connectivity momentarily while verifying the Dropbox API request, which causes the linking process to fail.
Will changing my Dropbox password fix the linking issue?
No. If the problem is caused by background data restrictions or corrupted app installation, changing your Dropbox password or switching between Wi-Fi and LTE will not resolve the connection failure.
Can I use another app to read my Dropbox PDFs on a tablet?
Yes. Many alternative PDF viewers and document editors, such as WPS Office, feature built-in Dropbox integration and can be used to view or edit your cloud files smoothly.
