The “Unable to connect to world” issue may be caused by internet problems. It is possible these situations may interpret your connection to your friends’ world: servers are full, your area has certain restrictions that may affect the connection, etc. Then you can use a VPN service to solve the problem.
Why when I try to join my friends Minecraft world it says unable to connect?
First, check to make sure you are connected to the Internet. If you are not connected, try connecting to a different WiFi network or using your cellular data. If you are connected to the Internet, try restarting your device. If you cannot connect to a world, try deleting and reinstalling the Minecraft app.
How do I fix unable to connect to a Minecraft server?
Try disabling any existing firewall program, or changing its configuration options. Restart your modem/router. You may also want to try logging out of your account and then logging back in, as this refreshes your profile’s authentication and connection with our servers.
