While using Safari, I frequently receive the message "Certficate Not Valid, may be directed to an external page". This happens when I try to access a page from a google search menu.  What does this mean and why does this happen?  It doesn't happen with the Chrome browser.

Software/Hardware used:
Safari, Certificate Not Valid

    Please try some steps that can help you to overcome this issue. Update Safari to the latest version/fix invalid certificate errors by repairing keychain.

    Hi Subhendu, it is updated to the latest OS Yosemite 10.10.5 version. I might have to switch to Sierra version. But what is the keychain?

    First exit from Safari. Now press command & spacebar to open spotlight search, then type keychain access & press enter key. Now on keychain access menu select keychain first aid and enter the user/ password(if asks). Here click verify box/start button. Choose repair.

    You might simply be browsing to websites for which the owners haven't renewed their SSL/TLS certificate. I'm seeing that more and more, including on websites for large companies that you'd think would've had someone in charge of this with something on their calendars to remind themselves to renew.

    Hi Subhendu - thank you for your reply. I will try your steps to repair the keychains.

    Kevin, So it seems like this is a normal occurrence. I never use to encounter this either...it is just within the last 6 months that this has happened. And you think it wouldn't happen for large companies.

    To rule it out try opening the same page on another system using both browsers. Based on the result, you can deduce whether it's to do with the browsers on your system or the web-site itself...

    Check the security setting in Safari.
