Syncing hangs every few days on Windows 10 Pro. System tray just says "Syncing..."

[drb01]

Dropbox used to work perfectly on this 2 year old Win 10 PC. But a couple of months ago syncing started hanging for no obvious reason. Every few days the icon in the system tray just says "Syncing..."., but it never actually uploads the files. The only way to get it syncing again is to quit (which can take minutes) and then restart Dropbox.

- There is no warning - I have to look at the Dropbox system tray icon. 

- I have tried "View Sync Issues" which says no errors

- I have tried "Fix Permissions" and "Fix Hardlinks" which makes no difference.

- I am currently using v115.4.601

- I tried re-installing Dropbox which made no difference

Any ideas anyone?

Hi there @drb01, thanks for reaching out!

Do you possibly have any antivirus software or firewall, running on this computer? 

Could you check to see if any Dropbox domains are being blocked by any of these services you might have running on your computer?

Let me know and we can go from there!

Hi - I only use Windows' built in antivirus and firewall software , and I haven't made any changes to their standard settings. Nevertheless I checked and Inbound Rules lists Dropbox and has "All" "Enabled". 

NB This problem only happens every few days, but once it has stopped syncing then it doesn't start again unless I restart Dropbox.

Thanks for checking on that @drb01!

I'd like to have a look into this with you further alongside some device specific info, so I've just sent a message to the email linked with your profile here.

Please check your inbox and get back to me there when you have the chance - cheers!
