Good morning! And thanks for the reply

Error messages received (If applicable): not getting any error numbers, I basically launch FF14, and the launcher app - where you log in - just shows "A connection error occurred. please try again later."
Wired or WIFI connection? My PC is running a wired connection; my laptop is on wifi on the same connection. This problem isn't showing on my laptop, but my laptop isn't good enough to run the game.
Are there other programs being used when running FFXIV? I've tried without any other programs open. I usually use the steam version, but downloaded the windows launcher to try without any other programs, and am getting the same issues.
When the disconnect occurs/How often? There is no disconnects; this is the first time this has happened, and it's been going on for about 17 hours now, everything was fine the day before this started.
Does this only happen to one character or all characters? It's not affecting any character, it's affecting my ability to even log in.

Thanks again for the help!
