Troubleshooting SSL error: Unable to connect to the site [...] authentic 
A few months ago some users are experiencing this error in Google Chrome browser preventing them visit some sites like Dropbox, Facebook, LinkedIn, Twitter or Google. Occurs during the use of Secure Socket Layer SSL. 
The error message in question, "Is there anything that interferes with your secure connection with the site" or "If you come now could share private information with an attacker" suggests that your machine has been compromised by a third party and that the browser has detected redirect some (most similar to a MiTM + + SET DNS spoofing attack). 
The problem also affects other browsers like Internet Explorer, although in this case the message is different. 
If Google Chrome, we are given a fairly generic url address where more information is specified as follows: 
There may be a problem with the certificate of the website. Maybe the certificate is missing, that is not valid or has an incorrect format. 
There may be a problem with the network connection or the firewall. 
These possible causes are not too resolute and do much more than confuse users, but just read the solutions that are being considered in several Internet forums (revision of the router configuration, temporary browser cache errors, malware no defined, invalid certificates, DNS servers wrong ...) 
So I think it's interesting to note some simple ways that you can help solve this problem:
1-Check the date and time of your system: the certificates have issue date / expiration date and your PC must be properly synchronized with an NTP server. The time service is an important issue, and can also cause errors in corporate environments that result in conflicts synchronization with Active Directory, limiting access to corporate resources, ...
2-Upgrade the operating system: the error primarily affects users of Windows XP, which incredibly, even to this date there is a utilization rate of approximately 26%. If applicable, check your service pack version, since it's probably a version lower than SP3 (update it). Microsoft has stopped supporting this operating system and you should change it to a more current version yet, wsusoffline can use to download the necessary updates.
3-Check your antivirus settings: although it should not interfere in your navigation wrongly, seem certain cases where the antivirus (BitDefender pe) could cause similar behavior in the browser has been given. You can check it momentarily disabling SSL scanning from the privacy control options.
4-Ignore certificate errors: indeed finally as temporary fix, you can run the browser Chrome going to -ignore-certificate-errors parameter. 
See you soon!
