My auto-scaling groups are stubbornly refusing to spin up when traffic spikes, causing chaos!

Alright folks, I'm pulling my hair out with our current auto-scaling setup; it's acting like a moody teenager refusing to get out of bed when the alarm goes off. Despite clear traffic spikes that should trigger new instances for proper horizontal scaling, our groups just sit there, leading to performance degradation and customer complaints. Has anyone encountered this particular stubbornness before or have any genius troubleshooting tips beyond the obvious? Help a brother out please...
