Sudden and Persistent Boot Error & Unable to Download

Hello!

I am stuck and need some help. After the emergency patch I have had a sudden error I am unable to resolve to play the game. I was able to login for a short period this morning but all last night and all during the day I have not been able to. Here are the steps I've tried.

1. Clearing DNS
2. Whitelisting FFXIV
3. Restarting Computer & Router multiple times
4. Running as admin
5. Reinstalling Microsoft edge
6. Deleting the patch folder to attempt to force re-patch.
7. Attempting to reinstall the game itself.

I have over 300gb of space so it's not a space issue either. Further, my wife's account on a separate computer, is exhibiting the same issue. But she has taken none of the above steps.

Now after the reinstall I can't complete the reinstall because it won't let me get through.

I have screenshots of the two errors. If I get through past the first error: (30605)(10009)(10020) then when I log in (or in this case try to reinstall) I get (11003)(10009)(10020).

Please help!

Good morning! Thank you for posting in the Final Fantasy XIV Technical Support Forums.

I'd like to get some more information regarding your issue.

Once we receive the requested information, we will be happy to look into it.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!

I'm also having this issue after the emergency patch. This seems to happen every time I data center transfer. I dc, then my launcher doesn't load properly or I can't log in anymore. I'm on a wired connection ATT fiber. No other programs running except my browser with twitch streams open. I've tried restarting computer restarting router. Everything seems to work except my 14. All the sites are fine but squareenix/14 pages load a bit weird.

Attempting to reload launcher gives me "A system error has occurred: 13. HostNameNotResolved"

"launcher.finalfantasyxiv.com's server IP address could not be found. Try: checking the connection - chceking the proxy, firewall, and dns settings"

I'm getting the same thing. Sometimes the launcher seems to make a connection, but then the launch screen itself does not always load or has a long delay loading. Once I am in the game it seems to run fine. This is specifically an issue with the launcher.

EDIT: I was able to resolve the issue by changing my Wi-Fi DNS server assignment from Automatic to Manual (using Cloudfare, 1.1.1.1 and 1.0.0.1). Windows 11, AT&T Fiber
