Can't Get Past Server Selection

[Sinphera]

Nevermind. It suddenly just started working. Well, not suddenly.

I logged in again after posting this, and it took me to a character selection with no characters on it. I exited, and then re-entered into P99 Green and was suddenly able to get back on fully without issue.

I would still like to know what could have caused this, since I haven't actually done anything on my end that would prompt it to randomly cause errors.
