I can NOT connect to any of my friends world in every device no matter what I do

My Minecraft bedrock CAN'T connect to any of my friend's worlds on cross-platform. I even try with my ps4 and mobile all with the same account and it still not. It always says "unable to connect the world" and I don't know what to do. I tried searching online and tried what they said but still does not work. My internet is no problem cuz I have 25 Mbps down, 20 Mbps up, and 39 ms ping. And everything on Privacy And one safety all allow, I even disabled my firewall, I tried everything that I know.
