Minecraft not letting me host/join other worlds

I can join anybodys minecraft game except for one friend. We cant join each others game and all my other friends can join me and him. He hosts most of our worlds so i have no purpose for this game until i can connect to him.

Nope it's only minecraft. I can join others world but when I get on one of my worlds it wont let anyone else join.

One child hosts the multiplayer world the other child cannot join that world, while on the same WiFi network. A friend of the hosting child CAN join the world via internet connection from a totally different home. I've already verified they can join mutiplayer games via parental controls.

Make sure you are doing the following:

Multiplayer Options

Minecraft (Bedrock) supports the following multiplayer options:

• Locally hosted multiplayer world via LAN or Xbox Live
• Realms
• Servers (unofficial, third party server software)

Locally hosted multiplayer world via LAN or Xbox Live

Any world can be a locally hosted multiplayer world, and accessible to other
Minecraft players.

To start, create new world or load an existing one. Then, select World Settings (pencil icon) →
Multiplayer → Multiplayer Game. If all players are on the same local network, you may also toggle on
Visible to LAN Players.

Other player(s) can join the world by navigating to the Friends tab and selecting the world.

We experience a complete freeze. When the account that freezes is hosting the world in splitscreen, all players and the world freeze.

When the account that freezes is the second player, not hosting the world, no one freezes.

When the account that freezes is hosting a world on xbox, and I join on my PC, only the xbox player freezes. I do not freeze on my PC, and the world does not freeze.

Hope this helps. Please let me know if you need anymore information.
