Er. 630 when trying to switch to PSO2 from NGS

I'm having an issue where I cannot get into regular PSO2. Either from the Character Select screen OR from the Ryuker Devices in NGS. It tosses up the loading tunnel and then I instantly get hit with Error 630. I had no issues swapping back and forth on Day 1... but since then, I cannot get into PSO2 and I'm missing out on my premium status log in bonuses and etc.

Anyone have any fixes I can do on my own?

Same here.

can't login on PSO2 : Error 630 Login on PSO2 NGS : ok Same here, it was working well, but now I can't acces PSO2 ! HELP !

Bump... It's still doing it after the most recent maintenance.

Same here on Ship 3
