iPhone alarm didn't go off this morning

Alarm was set, showed on the lock screen, and it just didn't ring. Ringer was on. Second time this month and I nearly missed work. Is there a setting that can silence alarms?

Few usual suspects, check them in this order: 1. the alarm sound itself is set to None (tap the alarm, look at Sound) 2. alarm volume is the ringer volume, so check Settings > Sounds & Haptics, the slider there was probably turned way down 3. if it was the Sleep schedule alarm rather than a normal one, that's set separately in the Health app Silent mode and Focus don't stop alarms, so it's not those. Set a test one for two minutes from now and see if it actually rings.
