The reason we are "Unable to complete version check" on PS4 is because the data packets from FFXIV servers get lost before reaching us, which doesn't allow us to update or check our launcher version. This is because of either a firewall or some protocol that was recently put up at the IP address 195.229.4.71 which is a point between Etisalat's server and FFXIV's PS4 servers (along the route that we send/receive data). Maybe PC uses different servers and that's why PC still works. That's what I understood from the 2 square enix tech support agents who actually know what they're doing. So Etisalat has to either request for that IP address to take down the firewall, or re-route their network settings to bypass that IP address.
