Safari can't verify the identity of the website

I would like to know how long that worked. I tried it and it seemed to help, but I would have to do this constantly for it to continue working. Why is that?

Hi guys, it's the time and date for me! Thank you! those msgs from every browser were so annoing!

My date and time are perfect and I still get the error ... Still only get it with my Wifi network.

The date and time did not work for me.

Thanksssss, it worked 😀 😀

This totally worked for me.

Ok - a quick reply. I have to resolve an issue with the AppStore - UPDATES fail to verify the preflight file and I get a message that it is not signed by Apple. Stand by,

Thank you Wayne :)

Thank you so much dbsneddon. I have been trying everything!!! I have having with a lot of sites load etc and it was simply that I had accidently changed the date on my computer.

Thankyou this tip really helped.

Thank you, leandroa!

I've spent few hours searching for solution, and here it is!

the date was not set correctly, thanks!

How do you locate a solution to a problem here?

THANK YOU! Setting "Priority" to "OCSP" instead of "Both" cured all of the certificate issues I've been having on Yosemite and El Capitan.

thanks, this way worked
