Workaround
This issue can be resolved by logging out of the launcher and logging back in.
The bug
I am unsure whether we already have a proper ticket about this, but multiple users have reported that they have issues logging into the game after they have changed the name of their account, as the name change does not immediately take effect in the launcher. This causes issues joining servers and similar.

I get that but know its been several more hours. and my ign still hasn't change and i still can't log on to servers,
Let's make this the main ticket about this. The issue probably lays in the way how the login system works. Session IDs. It's a key to contact the API and verify you're the owner of the account. The probably is that they don't refresh when you re-launch the launcher, only when relogging back into the account. So, that key is only able to pull out old information and not the new information (including the changed name). Probably the best way to fix this is to let the launcher check each time it launches with the public information on names, and if it doesn't match, refresh the session ID. I might be wrong on this, but that's at least how I think it should work.
