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.

Tried tinkering with everything. Seems my antivirus protection (ESET) has problems with Dropbox. Disabling the SSL protocol in ESET worked for me.

Quick solution that does not involves installing beta client of Dropbox:

Go to ESET Antivirus settings (F5) advanced settings > web and email tab > SSL/TLS > disable "allow SSL/TLS protocol filtering setting" (the first one) > hit okay button.

Hi:

I have a problem with dropbox sync since 2 days ago.

It shows "Can't establish secure internet connection".

I use Windows 10 and ESET NOD32 A-V.

I have Dropbox allowed in windows firewall and I've tried to disable the firewall and the A-V.

I have the proxy configuration disabled in Dropbox.

Any idea?

Thanks in advance.
