"Dropbox cannot start / Dropbox ran into a connection issue" error (macOS Monterey)

Hi,

Dropbox app used to load at startup and work smoothly on my Mac but since a few weeks Dropbox can’t load at startup, giving the following error dialog: 

"Dropbox cannot start / Dropbox ran into a connection issue"

I click OK and get another error dialog: "Couldn't start Dropbox. This may be a temporary error. Please restart Dropbox. For more information, click the help button.” so I get the error log (see below) and click OK.

 

After these steps I’m always able to open Dropbox app from the Applications folder and everything works fine.

So, my issue is only at startup time, when some sort of "connection issue” happens.

 

Please be aware that I’ve already done an advanced re-install (twice!) and all the necessary Accessibility/Full Disk Access/Files and Folders settings are ok.

 

Could you help me?

 

Thanks,

Davide

    Hey Davide_Saraceno, thanks for bringing this to our attention.

     

    Can we send you an email, so we can investigate this a bit more closely?

      Hello,

       

      since the last big update of Dropbox (moving whole user's stuff from <user directory>/Dropbox into Devices) I often get the same errors.

      The update itself succeeded, so I guessed everything would be fine and indeed under the Section Devices I have access to all my files stored in Dropbox.

      Before posting my dropbox_error.txt file I want to mention one point that I was aware of reading the error file. It is the lines:

       

      trace.__file__: '/Applications/Dropbox.app/Contents/Resources/python-packages.zip/dropbox/client/ui/common/boot_error.pyc'
            real_path='/Applications/Dropbox.app/Contents/Resources/python-packages.zip/dropbox/client/ui/common/boot_error.pyc'
                            not found
                      parent not found

       

      ... and look at the subdirectory python-packages.zip as part of the long path specified. So indeed there is an existing zip archive in the middle of the path and obviously all next subdirectories and consequently the root file boot_error.pyc cannot be reached.

      It's now the question if this leads to the last error in the dropbox_error.txt file or not (see last line below)

       

      I append the whole dropbox_error.txt:

      Hi,

      Since yesterday Dropbox can’t load at startup, giving the following error dialog: 

      "Dropbox cannot start / Dropbox ran into a connection issue"

      I can only access my folders online and the desktop app is not running anymore.

       

       I’ve already re-install three times the app in my desktop and nothing has changed. It appears the same error.

       

      Could you help me?

       

      Thanks,

      Carla

    Hey SS71, sorry to hear about this.

     

    Can you please let us know if you rebooted your computer since you first got this error?

     

    If you did, have you tried reinstalling it?

     

    Let us know of any updates!

      Hello,

      Yes, I did reboot the macbook pro and deleted and reinstalled Dropbox without much luck.

        I had the same issue and neither rebooting nor reinstalling solved it. The only solution in my case is to run the older version of Dropbox and NOT update it to the version, where the storage location is changed to the new "cloud storage" section on the filesystem. There really is something going wrong with the new Dropbox version for macOS.
