Dropbox stopped working on my android phone. Tried a different network but still wouldn't work/sync/etc. Uninstalled and re-install it onto the phone. Now I can't login. I get the following message. "sign-in failed. Unknown error, please contact Dropbox customer support" I tried changing my password via my laptop then signing in on phone with new one. Still get the same message. Working fine on both my laptop and my Surface tablet. Reinstalled twiced but get the same message each time.

Solved it myself.I installed it, clear the phone's memory, turned off the phone. Then when I turned the phone back on, re-installed Dropbox. It worked, and I was able to finally login.

Hi SuzyS, thanks for joining the Community!

This is what I would have suggested as well, uninstalling the existing app, rebooting the device, and re-iinstalling it again.

I'm glad to hear you were able to resolve it on your device.

If you need any further assistance in future, please let me know!

I recently began getting an error on my Google Pixel 5 - Sign in failed - Unknown error. I am using basic version of Drop Box and only have two computers linked to my account. Cannot figure why I cannot log in.

Hey rssear17, thanks for nudging us on this thread.

Could you try signing in from a different WiFi network or by using your cellular network?

If you're still having trouble with this, send us a screenshot (without any personal info) of the error message.

Successfully installed & used password app on my Win10 laptop and my old Galaxy phone for 2 weeks. I am having issues logging in on my new Pixel 5. New phone sends notification to laptop but gets an error message after I confirm on the laptop. Error message reads “Oops! An error has occurred, please try again later.”

I have uninstalled, cleared temp files, restarted & reinstalled multiple times.

Hi orthobio, thanks for joining us on this thread.

Could you try signing in to the mobile app on your Pixel 5 device from another WiFi network or by using cellular data?
