[Zeric97]

I recently just upgraded from playing the free trial to having the complete edition and now i cant get past the login on the launcher and everytime I try i get a "unable to complete version check"

I was playing the game last night and now i cant play at all!! Help please!!

Also ive tried about every fix ive found on this forum and nothing works

the only one i havent tried is calling isp to forward ports but if i was playing last night i dont see why it would be an issue now.
I play on steam

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

Please try the following troubleshooting steps:

- The game will use the Internet Explorer web browser to connect to the internet. Open Internet Explorer, then open the "Tools" setting, go to "Internet Options" and adjust the following settings:
- Under the "General" tab, please delete ALL browser history.
- Under the "Security" tab, please move the slider to the lowest possible settings or no higher than "Medium"
- Under the "Privacy" tab, click “Advanced” and select ‘Accept’ under both First Party and Third Party Cookies.
- Under the "Advanced" tab, please make sure that "Allow software to run or install even if signature is invalid" is CHECKED.
- Make sure that all SSL and TLS (EXCEPT SSL 3.0) are CHECKED. [SSL 3.0 should be UNCHECKED]
- Hit "Apply" to save the settings, and then "OK, to close the Internet Options menu.
- Please RESTART your PC now. Once your PC has been restarted, Right-Click the FFXIV launcher icon once more and select "Run as Administrator"

-Make sure your fire wall or antivirus program is not interfering with the game

- 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 am having the same issue. I've attempted all of the above but still receiving the same error code.

Is there anything else I can try?
