Dropbox Won't Start - Stuck on Connecting / Starting

Hi HTDUCK; welcome to the Community!

If you've ensured that there's no antivirus, a firewall or even a VPN/proxy setting that could be causing this, you may need to perform a clean, advanced re-install.

Before you get to that though, could you try unlinking and relinking your account through the app's preferences? Maybe that will do the trick.

Keep me posted!

Hi Walter - Thanks for the response. There are no anti-virus, firewall, VPN or proxy settings on my home network (I've tried connecting with the Mac's built-in Firewall both on and off, and it makes no difference). My latpop is setup exactly the same as my desktop and it connects without issue. I did try unlinking from dropbox.com. But unfortunately I cannot relink my account through preferences as the Dropbox app simply will not connect to the Dropbox server.  It gets stuck on "starting" nor will it connect when I try to sign in to my account through it. I will try the advanced re-install and see what happens. I suspect the real issue was an Apple update over the weekend that changed something... but I can't pinpoint it.

Thanks for keeping us in the loop HTDUCK.

Whenever you get the chance, please let me know how the advanced reinstall worked out for you and we'll take it from there.

Enjoy the rest of your day in the meantime. 

I tried doing the advanced uninstall/reinstall with the recommended Mac terminal entries, and that didn't work. Same result. The Dropbox app cannot connect to its server. Tried another solution from the community here, removing everything including files stored locally on my Mac, etc. and that didn't work either.  

I'm at a loss other than upgrading to Catalina 10.15.7, nothing on my computer has changed since Sunday (when it last worked). Every other internet connection works just fine. I have tried turning off the Mac's built in firewall, etc., and that made no difference for Dropbox (when installing and otherwise). I have tried setting Dropbox to "no proxies" and that didn't work. I am running on a home network, with other computers that can access Dropbox without issue, so I know it's not the router, including a MacBook running High Sierra.

The only conclusion I can come to is there is some issue between Dropbox and OS Catalina 10.15.7.  The previous version of Catalina was working just fine (10.15?). 

Thanks so much for keeping me in the loop on this one HTDUCK. 

At this point, could you try the following:

1. Click on the apple icon in the top left hand corner of your screen
2. Select "System Preferences..."
3. Then "Security & Privacy"
4. Select the Privacy tab
5. Select "Files and Folders"
6. Under Dropbox ensure all folders are checked

To make changes you will need to click on the lock icon and enter your macOS password.

Now attempt to restart the Dropbox desktop app.

Let me know how you get on!

Thanks for keeping me in the loop HTDUCK; I'm glad to hear it's working fine again!

Enjoy the remainder of your week and see you around the Community :coffee:

I'm having the same problems, but with windows 10. I tried all steps mentioned in this thread, downloaded updated app and reinstalled it, disconnected the computer from the website, restarted the computer, nothing seems to work...

Hey, I have a major issue, where my dropbox desktop app. thinks I am offline, and there seems to be no way I can start up the app, let alone sign in. Anyone else had this? 

Many thanks, Leila
