I'm definitely not a techie but I know there are alot of updates going on now with the Ark Moon and other things so it may be simply you are caught up in a update loop...don't know the tech name for it but I know when they do a larger upgrading, I have to relog several times to get to the launch screen which seems to get "stuck" and eventually, I can get past the launch screen (with the green dot on top which means "ready", not red which means offline) After an update, it also takes longer to sign back on the first time after the update has completed.
I don't know if any of this helps but I hope you back on into the game.
