Re: Cannot establish a secure connection

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...

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).

You are probably right! The new year is an *ideal* time to roll out more security protocols and break something! Thanks.

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.)

 

Either way, your suggestions are much appreciated.

Omg Yes! it worked! i haven't been able to connect discord and at one point i couldn't connect One drive. Weird to think it was the proxy .-.

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.

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.
