Dropbox can't establish a secure connection.

[rmfh]

Dropbox was working fine on my MACs (high serria)

now they all say can't establish a secure conection. I have switched off my firewalll and Antivirus still get error.

I have now unistalled dropbox dowloaded the lastest and it fails to install with a no internet connection error.

Any ideas?

I've also checked my proxy settings.

Checked the time on the computer?

If so have you looked at https://www.dropbox.com/help/desktop-web/cant-establish-secure-connection ?

[rmfh]

Checked all those settings are correct. must be somthing else.

I have already checked with the Antivirus and my ISP both say its not them. 😞

Hey @rmfh! 

Have you by any chance tried rebooting the router or re-installing the Dropbox desktop application with the offline installer? Maybe that will do the trick. 

If the issue persists, can you provide us with a screenshot of the error so as to have a better understanding of the situation?

Thanks in advance!

Hi,

I upgraded my dropbox to version 52.4.6 and changed the version of my anti-virus and changed my Plusnet DNS server.

Now all seems well.

Need all three as no one of the changes worked in itself. Tested on two MACs both High serria.

W7, 64bit, Home Premium. Updated to 57. 4.89.0, with off line installer, rebooted, restarted. still no sync "can't est. secure connection."
Then stopped and restarted dropbox, no sync. Now what?
