Hello! Whenever I open the FFXIV launcher, I'm greeted with this cheery error.



Googling the issue tells me the problem has something to do with the service that handles the launcher, Frontier. I've tried a number of suggested fixes, including...

Pressing yes.
Pressing no.
Restarting
Turning off my antivirus (Avast, Windows Defender)
Whitelisting several IP addresses (from 2015, before the server move) and "http://frontier.ffxiv.com/*" in Avast's "exclusion" menu.
Changing my default browser from Chrome to Internet Explorer
Clearing my cache in Chrome
Running the launcher as an administrator.
Changing FFXIV_BOOT.cfg (C:\Users\[me]\Documents\My Games\FINAL FANTASY XIV - A Realm Reborn) B4EulaAgreement from 0 to 1.

... To no avail. The web address frontier.ffxiv.com is giving me and others 403 errors, which may indicate a serverside issue, but I'm posting here to be thorough.

Thank you in advance for help.
