Make sure you and your friend are both running the same version of Minecraft PE. Version differences, particularly if one of you is running a beta version, can cause disconnections. Update both devices to the most current version to ensure compatibility.
Minecraft PE does not support multiplayer natively via mobile data. Players frequently ask for this, but currently you must connect Wi-Fi or a personal hotspot. A stable internet connection is also essential. If you or the other person has a weak or unstable connection, it can slow down joining. Attempt to restart your routers or use a different network. Something like a mobile hotspot just to check if that makes it work.
Verify your in-game settings to make sure multiplayer is on. Go to Settings > Multiplayer and ensure that “Multiplayer Game” is turned on. Also, check that your Microsoft account permissions permit playing games in multiplayer.
Occasionally, the security software may disconnect Minecraft’s connection. Make sure your firewall or antivirus is not blocking the game from getting connected to the internet. You may need to insert Minecraft into an exception list or turn off the software temporarily for the purpose of testing the connection.
Sometimes the friend list has glitches. Try removing and re-adding your friend to refresh the connection. Navigate to your friends list, delete the friend, and then add them back by their Gamertag.
Some custom skins can sometimes be problematic. Try changing to a default skin, such as Steve or Alex, to see if the skin is to blame.
Network Address Translation (NAT) settings may influence multiplayer connection. Make your NAT type open or moderate. Modifying router options or activating UPnP (Universal Plug and Play) may help.
Both devices should be compatible with the game’s requirements and possess sufficient resources to operate multiplayer sessions. Older devices may have problems with newer versions of the game, a probable reason why your friend can’t join Minecraft PE World.
If you are on a server or realm, make sure it is on. And that the two players have permission. Occasionally, server-related issues may bar connections. Infrequently, but at times, Minecraft’s huge number of players also creates irritating server problems due to server overload. The ideal course of action here is to wait.
As always, uninstalling and reinstalling Minecraft PE can cure stubborn problems. Be sure to save your worlds before doing so to avoid losing your data. One of these solutions should help fix the problem for you. If you are curious to know more about Minecraft, read about how much money Minecraft just made in with the film adaptation of the game.
