Unable to complete vesion check. [30410] [30607] [20457] [404]

I keep getting this error message, and I've tried everything.

Picture of the error message: https://gyazo.com/d434ea6bc16e0d68af95b3908ee1ef8c

Things I have tried:
- Fixing settings in Internet Explorer
- Turning of anit-virus
- Turning off firewall
- Changing to mobile hotspot
- Running as admin
- Editing FFXIV_BOOT
- Using the registry editor
- Connecting directly to the router

I'm not sure what else I can do at this point. I can try to re-install the game, but I have read that it doesn't always work. I dont want to take the risk unless absolutely necessary.

I would really appreciate it if anyone could help me.

EDIT: Problem fixed

I found no other way to fix the problem, so I decided to re-install the game. This luckily seems to have worked.

I have the same issue here as well, i have tried everything except for reinstalling and i have seen a prior post of someone reporting the same issue... i am just not sure what i can do anymore, i am too scared of reinstalling the game in case it doesnt work. Hopefully they will see it soon

Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

Please try the following troubleshooting steps:

- Check to see if the following port ranges are opened on your router. You can contact your ISP and request they open them for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040

-Try disabling background applications and do a clean boot by opening the task manager and selecting the “Start up” tab. Disable everything and then restart the PC.

I tried disabling background applications, but that didn't work. I can't get in contact with my ISP at the moment, and it's starting to get late. I will post an update if i get in contact with them tomorrow.

I tried opening the ports, but it still doesn't work. I got in contact with cosutmer support and was told to open some more ports, but that didn't work either. I think i'll just try reinstalling the game. I will update you when I'm done.

I reinstalled the game, and that seems to have fixed the problem. Thanks the help!
