UPDATE:
Issues solved.
The issue was a registry key added by a Microsoft EasyFix (51044 to be specific) that modified the way TLS was being used.
It basically forced TLS 1.1 / 1.2 instead of the one required by the launcher making it unable to check the files and signatures and thus returning the errors above mentioned.
The solution is to change some registry keys to force windows to use ALL of the TLS version allowing the launcher to file check and eventually update the game.
How to solve the issue:
- Start menu > Type "Regedit" (no " of course)
- Navigate the left panel to this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp
- Once you click the WinHttp on the left panel, you will see that the right panel will show DefaultSecureProtocols
- Double click it and change the "a00" to "a80"
- Navigate the left panel to this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp
- Once you click the WinHttp on the left panel, you will see that the right panel will show DefaultSecureProtocols
- Double click it and change the "a00" to "a80"
- Close RegEdit
...and now you should be able to pass the version check, update and play the game.
Just in case, im gonna add some META TAGS that are HIGHLY related to the issue as this easyfix is used for some other games and softwares related to those games. I'm adding them to make it easier for FFXIV players to find this fix and continue playing.
Feel free to remove them if against any rule.
