Wi-Fi Network Can't Connect to ID Servers, why?

Wi-Fi Network Can't Connect to ID Servers

I tried asking Apple Support but not really much luck. My wi-fi network can't connect to the AppleID server, meaning that authentication for Messages/FaceTime/iCloud fails when I try to connect. It's across all my devices (MBP, iPad, iPhone 6). When I disconnect my iPhone from wi-fi, it works. I tried restarting my network and all my devices to no luck. Has anyone else had this issue or found a solution? Thanks!

Do you have any firewall or blocking services like openDNS active that may be preventing it?

OP here. I checked that, but no luck. Everything there is okay.
