FFXIV Boot Error & FFXIV Launcher issue

I have been playing a ton in the past week. Last time was 7 hours ago. This morning I tried to launch the game as I do multiple times a day and hit my nose on this :

"Unable to complete version check. [30605][20448][10009][10019]"
or
"Version check failed. [...] [30605][10009][10020]"

I have looked online, found and try different options.

1. I tried disabling both my firewall and anti-virus for the duration of a try.
2. I tried whitelisting every component of the game.
3. I tried editing the FFXIV_BOOT.cfg file in note pad by changing "BootVersionCheckMode 0" to "BootVersionCheckMode 1".
4. I tested my internet connection and tried another one.

When option #3 is on the table, the error message changes sometimes to "A system error has occurred: -2146697211. HTTPS System Error."

During the different tries, I got to the launcher twice. Once every line was changed to a "no connection" line of some sort. And another time I could see the rolling menu with the ads, but the same error pop-up showed up. When these happened I closed the launcher and launched it again to the error message before reaching the launcher.

I am now at lost. I paid a few months for nothing in the past because I could not update the game (a relay tower in a town two hours away was named as the cause by SE before telling me it was my problem). This time I do hope something is possible.

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

Thank you for this answer. Unfortunately it is not my first rodeo and all these steps were already done. I confirmed each and everyone of them to be certain.
