Log in error (Fb app & messenger)

Good day! When I log out my account yesterday, and then I tried logging it again, I cannot go through with it in the Facebook app, but I can log it in Safari. Same as my messenger app, it appears “log in error. An unexpected error occurred. Please try logging in again.” I tried restarting my phone, reinstalling the app, but it didn’t work as well. Kindly refer to the image attached. Thank you
