Meeting friends problem?

Br

My 2 year old has a really hard time making friends, but it’s not because of her. Idk if it’s the area I’m in (north Georgia super kid friendly area) or what?? We’ll go to the playground and stuff and she tries to say hi to every kid and they just stare at her and walk away. Is this normal? I feel so bad I want to cry. She seems fine with it but she honestly has no friends and I don’t want it to affect her 🥺
