I provide my usual advice. Volunteer. It's local, you meet people, usually the kind of people who Volunteer for things (meaning good people). Even if you don't find a date it can build your social network which will help.
As for specially fellow Ace people you may try pride, or LGBTQA+ events. Somtimes (the ones that accept us) will have some Ace representation.
One alternative may be to look in the Nerodivergent spaces, if you happen to a part of that community.
Not to assume. But someone back on reddit mentioned that a study had shown disproportionate number of us are in the autism spectrum. This is true in my case and with the few other Ace I've met offline. When I eventually get back into dating I may give Hiki a shot along with the volunteering.
