A few days ago Dropbox Desktop (Basic plan) stopped synchronizing with the cloud: neither files that I update in my computer are uploaded nor files that other upload into the share folders. The message that appears is "Reconnecting to the internet. This may take a moment". Nothing has changed in the PC, no updates, and the network works well except for this. There are other, older posts with similar issues, but I have not seen a solution so far. They mention a problem with the firewall, which I check and does not seem to be my case.
Any advice on how to address this?
