There are some web address that seems impossible to unblock, for example:
“c.whatsapp.net” “media-fco1-1.cdn.whatsapp.net” “edge-mqtt.facebook.com” “lithium.facebook.com” “b-api.facebook.com” etc… all these requests come from smartphones.
I can see them in the Internet Logs and the reason of the blocks is “Proxy/VPN”. For some of these the port is “TCP:80”, for others “TCP:443” or “UDP:443”.
I write them (in every way) in the white list but they can’t to be unblocked.
Try it yourself: Take a mobile phone and just sent a message in whatsapp or just open the facebook and messenger app. If in your parental control are active Literal IP Addesses, Proxy,VPN,Tor you’ll have those addresses in the internet logs. Then copy them in the white list. They will not be unblocked.
