FFXIV Launcher Error [30246][19900][740]

[sideshowsam]

Am unable to launch game and am given said error.

This is what I've done so far

-Move game to a different drive
-Fully reinstalled
-Ensuring all needed router ports forwarded
-Using a VPN
-Turning off antivirus protection
-clearing all history/cookies/etc from IE
-checked that everything is running as Admin
-Reinstalled game a 2nd time.

Error started randomly this week, no new hardware or changes.
Never had this problem, running game since Launch day.

Thank you for assistance!

Try using a different network, this has fixed it for me in the past. I tethered to my phone just long enough to get the launcher up and it was fine after that.

Thank you for the suggestion, and I used my phone to do likewise. No luck, I'm afraid

Darn. Are you on anything that uses the Intel I225-V network adapter? This is really reaching here, but the latest driver for that thing is bunk and I had spotty/no network connectivity. It's used on both Intel and AMD motherboards, I had to rollback the driver, and then stop driver updates via Group Policy. Unfortunately it's actually a really common adapter so idk, mebbe have a look.

Nope, I use a E2500. Must be something else

After a fresh install, I can launch the game 1 time. After which upon logging out, the errors return

Thank you for posting in the Final Fantasy XIV Technical Support Forums, sideshowsam.

These errors may have to do with connection stability, have you removed the patch folder by chance?
(My Documents > My Games > Final Fantasy XIV > Patch Folder)

Is the FFXIV folder set to 'Read Only'? (Please be sure to uncheck this option to allow 'Read & Write')
Does your anti-virus software have the proper exceptions when launching the game?
Have you reset Internet Explorer/Microsoft Edge Settings to see if this may help?
