After update I've very very strange problem, site only works in Google Chrome, Safari & FireFox can't open website, They Can't connect to server, then i try to access from mobile (same Wi-Fi network and also on LTE - works perfect )

"Safari Can't Connect to the server"
"Firefox can't establish a connection to the server at"

I also try :

Clear all history & coockies - the same problem
Restore All website
