FF14 is one of the few MMORPGs that has really done well. Because of its interesting story, colorful characters, and tons of exciting quests to go on and powerful items to get, it has not only lasted since it came out in 2013, but it still brings in millions of new players every day.
As with all online games, though, errors and other problems can sometimes stop you from playing your favorite games. One of these is the FFXIV Launcher Error 503, HTTPS System Error Issue.
Players sometimes get this, and they want to know why and if there is anything they can do to fix it. If you’ve also been getting this error, this guide will explain why it’s happening and what you can do about it, if anything.

FFXIV System Error Has Occurred 503, Launcher Not Loading
When you try to run the game, you will instead see this message: “A system error has occurred: 503. HTTPS System Error.” The game won’t start, but the launcher will close.
So why is this happening to begin with? Well, this error seems to happen when a lot of people play the game at once. This usually happens after a big update to the game, usually in the form of a new patch. Players then rush back into the game to check out all the new features and changes.
This means that the FFXIV System Error 503 is caused by servers being too busy, which is also why this connection error keeps happening. There isn’t really a way to fix it. All you can do is try to restart the launcher until you can connect and get into the game. If this doesn’t work, you should get in touch with Square Enix support for more help.
