Woke up and now I’m back in. Happy it’s working but it absolutely sucks because I really needed to access my files last night.

I'm having the same issue on my new iPad Pro. I can log into the website fine, and I can also access Dropbox on my iPhone 8. I just can't log in on the iPad, I keep getting the 400 error message. Help?

I did delete and reinstall it but that was only on the iPhone. It’s working again on both devices.

Hi,

 

Can you share the info located at the log file:

 

on ipad/iphone

 

Get crash logs directly from your iPhone/IPad

  1. On your iPhone/Ipad, navigate to the Settings app
  2. Go to Privacy
  3. Go to Diagnostics & Usage
  4. Go to Diagnostic & Usage Data
  5. You will see an alphabetical list all crash logs on your device
  • Hint: Once you’ve entered the crash log, you can long-press to select all of the text and copy to your clipboard.

Cheers

 

JR

Sorry, another question:

 

Have you updated iOS and your apps to the latest release?

Sounds like theres been a slight downtime overnight.

Pleased its all sorted.

TreyInSD - could you try a reboot of your devices and try again? If that doesnt work I suggest logging a ticket at support - www.dropbox.com/support which you can then track at http://dropbox.zendesk.com

Wow! Glad to know I wasn't the only one. As of this morning, dropbox is now working. But, I'm still having issues with its connection to LiquidText. But, I think that's an issue for them, not here. I did need to work last night, too. Oh well. Glad its working now!

Make sure you are using the most recent versions of LiquidText - older ones probably wont work now as Dropbox depreciated some old API recently

Yes, I was. I was also logged on on my other iPhone (also running current software). It was really bizzare! Thanks for responding though!
