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

[Davide_Saraceno]

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?

[Davide_Saraceno]

@Hannah sure! 

Thanks,

Davide

[Hannah]

Not a problem, Davide, I just emailed you, so we can continue from there.

Thanks!

I have the same issue after rebooting my Macbook today. Any solution for this issue?

Hi @miguel camacho, in order to look into this matter in more detail, would it be possible to reach out to the email associated with your forum profile?

Hi @Jay, yes thanks for the reply. How can I share with you privately the email associated with my Dropbox account?
