Unable to download patch files.

[umbrellaclown]

I was just having this issue (and might have a solution)! I have a theory that I'll post later, but to help us all figure this out:

Are you running Windows?
If so, could you please Start Menu -> Run -> "cmd" (enter) and type "nslookup patch-dl.ffxiv.com" (enter)?

Please post bottom resolved portion here (right click, mark, drag the area for copy, hit enter). Mine looks like this:

Non-authoritative answer:
Name: a1441.g.akamai.net
Addresses: 23.10.240.162
23.10.240.160
Aliases: patch-dl.ffxiv.com
patch-dl.ffxiv.com.edgesuite.net

Now Google "nslookup online" and put "patch-dl.ffxiv.com" in the nslookup site you choose (make sure it's different from the IP you're already getting).

Take that IP and add a line to your C:\windows\system32\drivers\etc\hosts file. It's hidden, so you may just want to hit open in notepad and paste the path in. You may have to run notepad as an Administrator to save that file. Mine looks like this now:

...
# 127.0.0.1 localhost
# ::1 localhost
2.21.246.19 patch-dl.ffxiv.com

The idea is that the Amakai CDN node we're being directed to for patch-dl.ffxiv.com might be having issues, so we go to another one by using the hosts file to redirect it manually.

Good luck and please post the IP you used if this works!

Also, please post the IP that didn't work. I'm assuming they're static and I'd like to start a list.
