Cannot establish a secure connection
Your computer will compare your system date to the expiration date of our SSL certificate. If your system time is stuck in the past or so far in the future that it is outside of Dropbox's SSL certificate expiration date, a secure connection will not be established. This is easily corrected by changing your system time to the current date...
There isn't anything for Dropbox to fix. Issues such as this are almost always caused by something specific to the computer, and are not a wider Dropbox issue that they have control over.
Possible causes are antivirus or firewalls interfering with the connection, incorrect date and time settings, etc. See the following help article for more information.
https://help.dropbox.com/sync/files-not-syncingIn updated and related news, I went into settings and turned off Proxy. Bingo! Now DropBox is updating automatically. (This despite the corporate firewall that evidently exists, or maybe I just imagined that.)
Either way, your suggestions are much appreciated.

https://help.dropbox.com/sync/files-not-syncing- sent me to correct help page about changing proxy settings. For some reason my Dropbox preference setting was on auto detect fro proxy. I didn't change anything, so i guess someone updated something and it changed or became an issue. Any way, changing proxy setting to no proxy and rebooting iMac solved the issue.
I am glad to see someone else is currently having this problem as well. Despite what one reply says, I do not think the problem is with my computer. I am not using any of the anti-virus they list and I am not going through any proxies. Specifically, I have gotten the message that my date/time is incorrect and that is why a connection could not be established. Yet I verified at TIME.GOV that my system date and time are absolutely current and correct. Now this is a "cleaned" used computer I bought recently and it is running Windows 7 Pro. Is Dropbox having issues with this older release of Windows?
- MarkNo it isnt as long as you are running a recent version of Dropbox from www.dropbox.com/downloading.
This has nothing to do with my computer. The date and time are set via a push from our corporate servers. Hell, I cannot even change the date on my box myself, anyway, due to log-in permissions. (Yes, our corporate security is somewhat, "zealous." Still, DropBox should not be giving me this error, since the date and time shown *ARE* correct.

An incorrect date and time are not the only cause of not being able to make a connection to Dropbox. There could be a firewall that is blocking the traffic (perhaps by that zealous corporate security team), antivirus, and many other reasons. Simply put, something either on your computer or on your network is blocking Dropbox. It's a local issue. If you haven't already, the first thing to try is to make sure that the Proxy setting in Dropbox preferences is set to No proxy (assuming, of course, that you don't use a proxy server).
In updated and related news, I went into settings and turned off Proxy. Bingo! Now DropBox is updating automatically. (This despite the corporate firewall that evidently exists, or maybe I just imagined that.)

... ?
Had the same symptoms on my PC. Turned out that I was running a program called Fiddler at the same time. Stopping that and restarting Dropbox fixed the problem.
