Safari can't open page for any website.
on my MacBook pro I get the error "Safari can't open the page.... Because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait a few minutes, then try again." For every page that I try to open or go to. This started for me last night. I have been on two different wifi networks in two different locations, and all my other products, including iPad and iPod, are able to connect and browse. Even Skype appears to work on my MacBook but none of my apple programs (Safari, iTunes, etc.) will. The computer is connected to wifi and running a diagnostic says everything is working fine. I have cleared all my history and cookies and removed all website data from the privacy menu. I have no extensions but turned that off anyway. I have tried restarting my computer a few times and it is still unsuccessful. i am not sure what to try next. Can anyone help me?
MacBook Pro, OS X Yosemite (10.10.2)
