The error message you are getting implies your Chrome browser cannot open a secure website because something on your computer is blocking it from performing the task.
If you are using a third party Security application to protect your system from virus threats, go into its settings and verify its not scanning https. If it is disable this.
If your Data & Time settings are inaccurate on your computer then any SSL certificates you have obtained from visiting a secure website will become invalid. So correcting the Date & Time [ if its wrong ] may resolve the issue. Note if it is wrong, you may need to get a new CMOS battery for your computer, as this information is preserved using that battery when the computer is powered off.
Something else you could do is clear Chromes cookies and saved data, by clicking the More icon [ top right corner of browser ], then selecting More tools > Clear browsing data. If that fails to improve things, you could instead select the More icon | Settings, then on left pane select to Reset and cleanup your Chrome browser.

Inside the Run Dialog window, type or copy & paste the following:
Press Enter key or click OK to execute the above command, which will open a new instance of Google Chrome that ignores certificate errors, and continues on to the secure website regardless. Note if the site requires authorization, you will need to sign-in with the correct username and password.
