Dunno what happened, but suddenly I cannot connect to Gmail from Chrome on this computer:

Gmail error on chrome

Under "more" it says:

What does this mean? normally uses encryption (SSL) to protect your information. When Chrome tried to connect to this time, returned unusual and incorrect credentials. Either an attacker is trying to pretend to be, or a Wi-Fi login screen has interrupted the connection. Your information is still secure because Chrome stopped the connection before any data was exchanged.

Network errors and attacks are usually temporary, so this page will probably work later. You can also try switching to another network.

Technical details has asked Chrome to block any certificates with errors, but the certificate that Chrome received during this connection attempt has an error. Error type: HSTS failure Subject: Issuer: ESET SSL Filter CA Public key hashes: sha1/LBVQpu3n4BwHoMqkrzfLxLsSnbI= sha256/RHmN1dbh3iUcYQqF0J9erDGWqz99PVYM//CxbUMbNbQ= sha1/WHrFP5oe9qirobGMRlG4wsHOHCI= sha256/leyNwItyakk42FEChQ4D3qwQ5FZvJorBZDZykIFzolY=

This only happens on Chrome; I get to the login screen with no problem on IE 11. And it's only happening on gmail; I can get to other Https sites on Chrome without getting this warning.

What is the problem? How to fix it?

Looks like Chrome doesn't appreciate what your ESET security software is trying to do (i.e., MITM'ing its connection).

You might try disabling ESET's SSL scanning.

If you're not running ESET, then you have more serious problems...

Yep, that did it. Weird, though, why suddenly did this start happening? Up until a couple days ago Chrome had no issue with ESET; then suddenly this error started happening. This is my wife's computer, and she certainly doesn't have the tech savvy to have fiddled with any settings! :-) – Shaul Behr Feb 23 '14 at 6:26
A new major version of Chrome came out a couple days ago, so that might be why. – jjlin Feb 23 '14 at 9:57
Hm, if that's the case, then we should start seeing a lot more pageviews on this question in the coming days... – Shaul Behr Feb 23 '14 at 10:09

I don't know what ESET is, but my wife's computer also suddenly started doing this yesterday. I re-synched the system clock (turns out it had been a month behind for ages) and restarted the browser and now it works again. – Isaac Betesh Apr 3 '14 at 14:28
  1. Check your system time - could be incorrect

  2. Once the time is changed (assuming it was incorrect), type "proceed" (no quotes) directly in the browser window (so you won't see what you typed).

It was the System DateTime for me. Thanks. – Arturas M Aug 13 '14 at 8:07
