FINAL FANTASY XIV Online: Error Message (Fix)

The problem

Is anyone getting an error message that is preventing them from launching the game, saying: Unable to complete version check. [30605] [20448] [10009] [10019]

Accepted answer

Please read the posted message on the official Lodestone. The login servers were taken offline for emergency maintenance due to the PhP security vulnerability

I'm glad I saw this. I can't even log into the official forums due to a 502 server error, which I assume is related. Hopefully it gets fixed soon. I've been trying to solve a crashing problem with one of my toons for the past few days while working with CS. It only affects one of my toons. Anyways, hope it is fixed soon. Hmmm.... the server status page says all green. Are they back up?

no this makes literaly everyone vulnerable, all it takes is 1 breach... a malicious actor could post a "patch" containing malware for the game or any other software that has automatic updates that you may have on your pc.

Well, it's not like FF wants to have the extra down time, it isn't exactly in their best interest to loose play time where you could be buying Cash Shop Items. They likely are taking extra precautions, or was worse off then Steam was. Of course it's worse. They probably have an ancient messed up login system they never bother to update ever. I won't be surprised if it takes a week or more for…
