Failed to save to the specified file

[thamesvalley]

Hi KeeAnywhere support,
I now have issue to save file to cloud.
I usually save the kdbx file to dropbox.
However, I got the following warning :

dropbox <filename.kdbx>
Failed to save to the specified file !
One or more errors occured.
The target file might be corrupted. Please try saving again.
If that fails save the database to a different location.

So, I checked the file, Indeed it is not corrupted.
I checked the connection from the Account tab and it displayed : Connecting to this account succeeded.
Each time I click "save to cloud" I got an error message.
See attachment.

Also, I'm required to kill the exe to stop the warning
How can I solve this ?
Thank you for your help.

I have the same error when I enable Cloud backups.

Local backups work fine though.

The same error only when I use Dropbox-Restricted settings.
Moreover, backup files actually are saved several times with intervals of a few seconds in local storage and imitate saving to dropbox, but actually, an old version is uploaded in a cloud.

The same error, re-add authorization verification, invalid.
