Unable to download patch files.[30413][25008][20495]

The installer ("Launcher" latest version) aborts and crashes with an error box when I try to re-install game after purchasing the full version with the trial uninstalled prior. In the middle of download, I get a dialog "FFXIV Launcher Error" box, that says "Unable to download patch files.[30413][25008][20495]", and then exits when I click OK on the box. I am forced to restarting the setup and try again / login and continue downloading. Then it happens again, and again!

Any fix? That's $29.99 wasted so far, 8 hrs messing with it + $100 in Crysta waiting to be used. Multiple emails and bug tickets sent, no ack from anyone, sad.

It's likely a network issue either on your side, your ISP's side, or somewhere in between you and SE.
If you're on wireless, try wired.
If you're on PC, you can try VPN services like WTFast.

I have the same problem. I reinstalled FFXIV to fix another problem and even though it was working fine with the EXACT same router settings as last week when I uninstalled, it will not patch.

Is there going to be a fix for this ever?
