Troubleshooting OneDrive Issues (“Can’t Connect” or “Bad Request”)

This is probably because Strongbox’s session has become stale. You can clear this by following the instructions below:

To do this on iPhone/iPad

1. Open Settings (tap the gear icon in the top right, above the list of databases)
2. Tap Advanced (at the bottom of the page)
3. Tap Manage 3rd Party Sessions
4. Tap to clear the session for your cloud provider of choice and confirm
5. Tap Done (in the top right of the screen)
6. Tap on your database
7. Enter your login details to re-authenticate

To do this on Mac

1. Click File (in the menu bar)
2. Go to Cloud Drive Sessions
3. Click to clear the session for your cloud provider of choice
4. Go back to the Database Manager window
5. Double-click on your database
6. Enter your login details to re-authenticate

Now you should be asked to login with OneDrive when you try to unlock your database. This will refresh the session and you should have no further issues.

It has been reported that sometimes even this doesn't help because the OneDrive app itself is installed on the device and it holds a stale session. In this case you should remove/re-add your accounts there and possible delete and reinstall the OneDrive app itself.
