Morphology
The meaning 'to prevent someone from sleeping' is directly derivable from the constituents: 'keep' (prevent/maintain) + 'up' (awake/not asleep) with 'at night' specifying the time. This combination follows a common English phrasal-verb + time phrase pattern that a B1 learner who knows the words would readily interpret.
Etymology
The phrase keep up at night comes from the simple idea of something keeps you up when you should be sleeping. Imagine a worry or pain that will not let you rest; it 'keeps you up at night', so the phrase means 'to prevent someone from sleeping'.
