Why does my optimistic main character feel flat and lack tension?

I’ve been trying to write a short story where the main character’s defining trait is their unwavering optimism, but I’m worried it’s making them feel flat and unbelievable on the page. Every conflict I throw at them just seems to bounce off, and the narrative feels like it lacks tension because of it.

I wrote a scene where the main character wakes up to bad news, and his hope stays but it's clearly not easy. I gave him a tiny plan—a kite that won't fly—so readers see effort, not perfection.

I shoved him into a storm of setbacks and kept the tone sunny, and the tension never lands. I ended up cutting a scene and leaving a gap.

Maybe the real problem isn't optimism; maybe the conflict isn't earned or the supporting cast isn't credible. I wonder if the problem is the goal: the story needs a real threat, not a mood.

I did try adding a flaw that travels with hope: a stubborn belief in signs and coincidences. The result: the character reads events as messages and misses the real danger until it's too late.
