Hello,
It seems like facebook is currently having an outage. Unfortunately, there is nothing we can do about this since this issue is on Facebook's side. You will have to wait until they have fixed the outage. As always, we highly recommend binding your account to an oasis account so this does not happen in the future.

(note that it says for Google but still works for facebook)
I already have a problem with step 1.
1: Sign in to your Google Facebook Account on the official website
You will be unable to do this if Facebook logins are not working. Please try now, they should be enabled at this point.
Yes, I was able to login to the website with Facebook.
Binded with Oasis account and can log in to the game again.
Thanks.
