Database will not sync over Dropbox

I have multiple databases syncing over multiple devices with dropbox. One of my databases will not sync with dropbox on only one device and has not synced since Jan 30, thus all the items entered into the database on this computer is not available on the other devices. The rest of the devices and databases seem to be working fine. Have tried to verify the database. Any thoughts on the next step? I don’t really want to delete the database from the device in question since I have added multiple items to it since its last sync.

And was anything reported, see also Window > Log?

Is repair the same as rebuild? Have tried to rebuild but nothing happens

Was able to get the database repaired

What kind of errors did the alert after using File > Verify & Repair Database actually report?
