Cannot establish a secure connection after dropbox update to 111.4.472

[gabriel_nemeth]

After the dropbox app (Window 10) updates itself to the latest 111.4.472 version, I'm getting this 'Cannot establish a secure connection'.

I've checked my time on my laptop, router. It's fine. I've disabled firewalls and the whole Eset Security. I've checked my ports. Everything is fine. I've turned off the proxy setting inside app. Scanned my system for viruses, nothing fount. The only solution is to revert back to the older version, but if I do so, the app will update itself so I'm at the beginning.

I am having the same issue with two different computers in different locations, different networks, but both using eset and windows 10.  I have also tried reinstalling the DropBox App and turning off my antivirus, but the issue remains.  This is urgent for me as well.

Dear friends,

I am the originator of this post, and after spending 9 HOURS today, I have the solution!

What did NOT work.... I changed my computer date, uninstalled and reinstalled dropbox, turned off proxy, turned off ESET and firewalls, and a zillion other things including reading every article dropbox has posted on this error message, and nothing worked!!!  I have windows 10 on both computers.

I then installed a beta patch from dropbox, which worked!!!!   here is the link to install it.

after installation, you need to reboot your computer, and then open dropbox.   then all files will sync and the error message goes away.

Merry Xmas to you all!  This is my gift to you.

Mod edit: If you're using ESET you can find the steps here.

I too am having the same issue after your last update. I have removed all instance of dropbox from my Eset Security as advised and still nothing. The issue is your end not on our systems as you would seem to suggest. Please fix ASAP

Thank you so much. I tried your way and it worked. Need not restart my computer though.

Same problem after an automatic windows update - Can no longer get a secure internet connection.
I have re installed the app, date and time are fine, internet is working, switched computer off and on.
Can anyone help?

Thanks
