If you use Dropbox as your primary storage, you need uninterrupted access to your files all the time. Sometimes, you may find that your Dropbox files are not syncing. If this happens, you won’t be able to keep your files in sync and your devices will have older versions of your files.

There are many reasons why Dropbox files are not syncing. Some of these reasons include your firewall preventing Dropbox from sending and receiving files, trying to upload restricted files, and so on.
