Dunno what happened, but suddenly I cannot connect to Gmail from Chrome on this computer:
Under "more" it says:
What does this mean?
gmail.com normally uses encryption (SSL) to protect your information. When Chrome tried to connect to gmail.com this time, gmail.com returned unusual and incorrect credentials. Either an attacker is trying to pretend to be gmail.com, 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.
gmail.com 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: mail.google.com 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?
