Got the same thing here and I'm on mac too
When i open my client all is good, then when i want to play on my charachter i click him and it just has my charachter moving like the loading screen and keeps saying "Connection failed! Retrying..." then it says "Connected" even though it isnt. I am on a Mac. This just started happening today, and on realmofthemadgod.com my account works. I have latest client.
