Tried logging in today and started getting this error code: np-36147-1 error

I'm in a PS4. Anyone else having this problem or is it just me? Any way for me to fix it? I've tried to repeatedly log in but get this error each time. Tried turning off my PS4 and still got this error. I checked the PSN network and its still online. And I checked the FF14's servers' statuses. According to their webpage, all servers are online. There isn't any maintenance going on.

Any help would be greatly appreciated.
