Mac: Dropbox Backup - "Error - can't backup this device"

I have an external drive connected to my Mac (iMac 2020. Big Sur 11.7.9. Dropbox 183.4.7058).  The drive shows up on the desktop and there're no issues with it. Approx 2 weeks ago it stopped syncing...

Hi Stretch1, sorry to hear you're having issues with this.

 

Could you try hovering your mouse over the error shown on your first screenshot? Does it give any additional information perhaps?

 

If you've already reached out to our support team about this, please let us know your ticket ID so that we can look it up as well. 

 

Thanks!

    Hi when I hover over "error" the text says "can't backup device. Plug in device again to restart the backup process"

    I have tried ejecting and remounting the ext. drive - it shows up on the desktop and functions ok but still shows Error in Backups

    Have also tried physically unplugging it, disconnecting the power supply and then plugging it back in, also doesn't work

      I'm assuming you've also rebooted your device Stretch1?

       

      If you did and this persists, please let me know if it'd be OK if we reached out via email to have a further look internally.
