I can't play realms or multiplayer servers and multiplayer and clubs are not blocked

I have multiplayer and clubs allowed on my Xbox and Microsoft account and it still won't allow me to play on multiplayer servers and realms. I have no parental restrictions, my internet and Nat type works fine, and all of my other multiplayer, online, games work just fine except for Minecraft. I have spent hours looking through settings and websites to try to fix this and it still won't let me play on multiplayer servers and realms.
