Welcome to the Community! I suggest your check our FAQ articles. There is not much information in your post around the device and so on, but you can find articles there like this one in case it's an Apple device.
Sorry for the delay in the response, we were getting some rest these days.
Have you tried connecting to the Kingdom instead of Facebook? There are no issues globally regarding the Facebook connection so it could be related to your own profile or something there that might be causing it.
We have some articles in our FAQ section that are related to connectivity, check around, maybe some can help you out!
If not, please come back with more information and we can keep looking into it together.
