My Windows 10 Dropbox app v. 169.4.56874 gets intermittently stuck on 'connecting' and displays a greyed out icon in the system tray. I have a fast wired Ethernet connection, I have allowed Dropbox in my firewall (the standard Windows firewall), no antivirus/blockers other than Windows Defender. Sometimes it connects, sometimes it just refuses. It is intermittent! I took it to the shop to see if they could resolve the issue, no luck. It is seriously annoying. I appreciate that there must be some app or setting that is blocking it (and which somehow it avoids occasionally) but I have no idea what. How do I check?
I have a laptop running the same version of Dropbox on W10 and this connects faultlessly every time.
