Same issue as OP, however I find I can log into my characters on Area 52 just fine. The issue is only with Elune, for me.
Tried clicking the cog at top right of launcher. Cleared the cache, and let it check for repairs. Didn't help.
Also, tried making a new character on Elune. "You don't have access to Character Creation on this realm. Please try again later, or unlock access to the realm if you do not have it already."
Recent hotfix seems to have resolved the issue for me. Working as Intended.
