I'm getting the error below every time I try to login to the Launcher:



On two other computers (and a PS4) at a different location (and ISP for that matter) everything works perfectly. This machine was working just fine 2-3 days ago. No changes had been made to this machine (not even any Windows Updates that I'm aware of).

I've tried uninstalling the client and reinstalling, and I still get this error. I've tried copying the game and launcher from my other, working machines, and no luck. I thought it might be Network related (had some issues downloading the game on a machine earlier today, and changing my DNS got around the issue). For networking I tried the Google DNS servers (8.8.8.8 and 8.8.4.4) and Level3 DNS Servers (4.2.2.1 and 4.2.2.2). Neither helped. I then tried connecting to my personal VPN that host (the connection where I have 2 computers and a PS4 working correctly), and then the Login part of the Launcher won't even load. The rest of the Launcher shows up just fine when connected to the VPN.

I'm frankly baffled, and starting to get really pissed at the game.

I've done some further testing. On the same network as the computer having issues I tried two additional computers. One was on the Networks Windows Domain and the other was not. Both of these PCs were able to boot the game. There were innumerable different things installed between the 3 computers, but the major thing was that the 2 computers that worked had not received the Content Creator update. I've tried the various Windows compatibility levels, running as administrator, deleting my settings files, changing my DNS and using a VPN. I'm out of ideas at this point.

I think this is related to your problem as I have run in to the same situation: http://eu.finalfantasyxiv.com/lodest...5a3469353ebe07

Don't think so. I've been having this issue since last week. It was working on last Tuesday, and then on Wednesday it was no longer working.

Well, I have no clue what was wrong with my computer, but I end up re-installing Windows due to other reasons and it works again. No clue what caused it, but hopefully it won't come back.

I also have this exact same problem. Unfortunately reinstalling Windows is not a solution I'm ready to accept.

The annoying thing is how I can install a virtual machine and it works, I can use my other computer and it works. There is no way it is a firewall/router/DNS issue under these circumstances.

Anyone else have the problem and know howto fix it?
