Most of apps (except Chrome) can't connect to the Internet
Safari, App Store, iTunes, and other applications can't connect to the Internet.
I've seen my proxy settings and they are all unchecked.
I've done a reset on my router and still no progress.
Safari keeps showing "can't establish a secure connection to the server...". Internet connection seems to be working fine because Chrome loads any website with no errors. Also, I've used my phone, tablet, PC to test the internet connection and they all got connected.
iTunes and App Store won't even connect. Now I can't buy and update apps, music, etc.
How can I be able to solve this problem? 😟
