I normally have between 2-4 bars in Houston and things load fine for me so it does not sound like a network issue. A quick Google search and some people are reporting the same error messages starting yesterday. I unfortunately do not use Facebook very much, have many of the notifications turned off online so not sure how that changes the Android app, but a few I get pop up in the top bar and I just click and they send me to a page to pick what I want to do.

You might try uninstalling the app (it comes pre-loaded I believe), and re-downloading from the app store to see if that works.
