Can’t host worlds, but can join other worlds, realms or servers (Minecraft)

It wasn't a realm world, more a server that my friends could join off of. Which suddenly stopped working game hosting wise, but I can join others fine with no issues.

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.

Thank you for your reply,

I tried to connect again, (Ping: 16ms, Download: 17mbps, Upload: 9mbps) with no drop in wifi. This is a realm bought from Minecraft (so I presume it is running off their servers). When I tried to join, other people were in the realm at the time.

Connecting to a friend's world normally works just fine (hosting or joining) but not realms.

“Join Multiplayer Games” Settings
If you have your settings set to block joining multiplayer games, you can’t join any multiplayer games in Minecraft, including shared local worlds, Realms or servers. To enable multiplayer in Minecraft, make sure this setting is set to ‘Allow.’

However, just like ASCllnaut, that setting was already turned on for my children. In other words I'm in the same boat, we can play on the LAN but not on a realm.

Hello Dear User

Welcome to the Microsoft Community.

I understand that you are having trouble on how to transfer your world from mobile to PlayStation, and I understand your confusion.

Transferring a world from Minecraft Bedrock on mobile to Minecraft on PlayStation can be tricky because there isn't a direct, official method to transfer worlds between platforms in Bedrock Edition. However, you can still do it with the following workaround that involves using Minecraft's cross-platform capabilities and Minecraft Realms or a cloud service:

Using Minecraft Realms

Minecraft Realms acts as a server where you can upload your world and then download it on another device (in this case, PlayStation).

1. Purchase a Realms subscription:
   
   You’ll need to buy a Minecraft Realms subscription. However, there’s a free trial for 30 days that you can use to complete this transfer without paying.
   

1. Upload Your World to Realms:
   
   Open Minecraft on your mobile device.
   
   Select the world you want to transfer.
   
   Click on the pencil/edit icon to open the world settings.
   
   Scroll down and select "Upload World to Realms" (you’ll need to sign in with your Microsoft account).
   
   Confirm the upload, and your world will be saved to your Realms server.
   

1. Download the World on PlayStation:
   
   Now, open Minecraft on your PlayStation.
   
   Make sure you are signed in with the same Microsoft account used on your mobile.
   
   Navigate to Realms and select your world from the server list.
   
   Download it onto your PlayStation console, and you can now play that world on your PS.
   

Using Cross-Platform Play (Multiplayer):

If you’re not keen on the idea of using a third-party tool, you can play with someone on the PlayStation console while hosting the world on your mobile device.

1. Create a Multiplayer Session:
   
2. Host a multiplayer session of your world on your mobile Minecraft (ensure both devices are on the same network, or use Xbox Live to connect across the internet).
   
3. Join the Session on PlayStation:
   
4. Open Minecraft on your PlayStation.
   
5. Log into your Microsoft account.
   
6. Go to the Friends tab, find your world, and join it.
   

This method allows you to play the world across platforms but doesn’t permanently transfer the world to your PS.

Please feel free to let me know if you have any further updates, thanks. 

Best Regards.
