Launcher/Account/Forum Login Issues Via Optus (Australian ISP)

Hello I've facing a bit of a odd problem, I am needing at the moment to turn on a VPN in order to login. It's not 100% of the time but it is often. I am aware of the Launcher Related issues for EU region master thread and as a Australian player playing on a Japanese Server I am unsure if my login is going through the EU services. However the issue has seemingly expanded to not just the launcher hence this thread

I need the VPN to login here to the Forums/Lodestone, to Login to the Mogstation and the Online Store. Any front end that interacts with Login Services when the issue is occurring requires me to use a VPN, in addition to the Launcher needing a VPN

Once I am logged in however, I can turn off the VPN and everything functions as normal. So I'm an Australian player who plays on Elemental JP (Account existed before OCE, do not wish to transfer), whose needing a VPN to login to with any of my account services/forums and to play. But once I am logged in I am okay to turn off the VPN.

So the issue is clearly via my ISP and wherever the login services for my account are hosted, as once I am *past* these login services I no longer need a VPN, so there isn't an issue with connecting to the website/game itself. It is JUST the login services.

These fixes did not work. Further research online has turned up the following info from other users

"So putting this in as a separate comment, but after multiple calls with Optus support they confirmed that due to the IP configuration of the launcher and websites they had placed a block on access. They have removed the block(for me) and I have not had the issue in the last 48 hrs. I will continue to monitor but if anyone is have this problem call Optus and tell them to remove the block"

and

"Talking to Optus literally right now and they are saying Square-enix / FFXIV websites and game log ins are banned by Optus as of December 2025"

So while I shall be contacting my ISP to resolve this directly I would appreciate if someone at Square Enix could ya know....resolve why their entire login services have being banned/blocked by one of Australias 2 largest ISPs
