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.

Hi everyone !

My main problem is now that Dropbox is saying that I cant establish secure internet connection. I tried every possible way to fix this problem. I changed proxy to no proxy, updated the app, uninstalled and reinstalled the app, ran compatibility on windows, changed the time on windows menu. This message comes only from one pc device, on the other 3 device dropbox is working very well without any problems. I would like to ask for your help, waiting for fast responses ! Thank you in advance, Zsolt

I had a chat with the support desk at Dropbox. They guided me through a procedure to install a new version - 112.3.254. It fixed the problem on both of my machines. I asked them to publish the fix on this thread of the forum. He said he will alert it. If nothing comes, contact the helpdesk.

I think Dropbox must solve the problem!!! It is something in their latest update that is the problem.

What I did for now removed the new ver. 111 and instaled the 100 ver.
But you have to force it not update by delete or even make a copy of "Update" folder and then rename or delete it . Becuase it keeps update it to 111. (For me and others this a temporary (future) solution)

I wish someone in Dropbox will fix it , I know this problems happend long time ago and it keeps happens again and again.
I also install in in my other laptop win windows 10  there it seems to be working good so far (few hours only)

For me it helped as a permanent fix - Link
Thanks @bioman

The problem seems to be in 111 new ver on windows 7, I install 100 ver and it works great. But I don't have I way to force it not to update to 111 part of delete "Update" folder 😞 

Please check it out.. it force me to stuck on older ver. for no reason. 
And I try No proxy , antivirus, date and time.
Thanks

New on my DropBox today - Cannot establish internet connection.

Reading the community, I guess it's from the latest version uploaded by DropBox.

I understand there is a Beta fax - when will there be an official fix??

I am getting the message "Can't establish a secure Internet Connection". I have been using Dropbox for years on this computer without probllems. I have paused my antivirus program (ESET Node 32). Downloaded the latest version of Dropbox. The time is correct on the computer. But still no good.

Did you try this (before my previous post)? Link
I have eset, but for now I don't want to mass things up.

@USB  Thanks for the link! Have ESET and that workaround did the trick
