How do I make myself less boring to women?

I've been trying to e-date for a few months now and the most common thing I hear is that I'm too boring. At first they appreciate that I'm mentally stable and not a deranged coomer, but things quickly peter out and I can't maintain their interest. I think I'm pretty good at holding conversations with people, ask them questions, get them to talk about themselves, make lots of jokes, etc but it never seems to last. It always ends up with me initiating conversations every time while their responses get shorter and shorter until I give up or they just flat out tell me that they're not interested any more.

Am I just pursuing the wrong women? Is it a "vibes" thing that I'm somehow failing at?

I'm not even autistic so I really have no excuse and I'm starting to worry that there's something wrong with me.
