The production server is back online with the latest version. Please make sure to have the latest client installed. At this time it is advised to use the "Download Now" button on the LOA Dashboard https://legendsofaria.com/dashboard to download and install the game with, as the standalone download has not been updated yet. See you in game!
Note: A common issue with the patcher seems to be that it fails twice but after the 3rd try it completes the updates. If you see "Patch Failed" just try re-loading the launcher and it should fail one more time, and then by the 3rd run be ready to play.
Tip: Untick "Verify Integrity" in the patcher after you've successfully launched the game and confirmed you can play. This will skip the lengthy scan that occurs every time you open the launcher. Turn it back on if you have crashes or errors playing the game.
