4 years ago I can't denied that blocking the b-api and b-graph will be occur the login attempt because I didn't mainly have any interests to use any official apps from Facebook, except Messenger Lite that doesn't having extra features (Stories, Games, etc.) and (maybe) advertisements that appear in the chat list, another reason is Facebook somehow wants to redirect to z-* (aka. Free Basics) servers when connecting from mobile data that also have Free (by trading our privacy and tracking your phone numbers regardless of already giving to them or not) services available in mobile carrier, such as Free Basics, Discover, ExpressWiFi.
However, I think I've moved into aggressive list already, so I have nothing to do for now...
Additional Edit: Consider to temporary whitelist both domain that you've reported or disable aggressive list before login is maybe good way to fix, any connections to those domain after sign into Facebook and Messenger aren't necessary anymore unless you're using main Facebook app that it's need to connect to those domains for retrieve news feed, also their advertisements as well...
Please note, you may need to disable or whitelist again after token reset time, expected 3 months for each interval that you need to reactivate your Facebook account credentials for contiue using apps from/with Facebook
