Whenever you try to join a LAN world It says “the host connection has been lost"

Whenever you try to join a LAN world It says “the host connection has been lost check your Internet and try joining again” or something like that, when you check the internet it is strong, but like if your sibling is hosting the world and they are right next to you, you can see their screen and they are STILL hosting, you try again and it still doesn’t work.

Please fix this.

I clicked send by mistake, don’t judge

Are there any resource packs or behavior packs applied to the world?

Even with no Resource packs or behavior packs on the world it doesn’t always work, if I empty my global resources it let’s me join then 5 minutes later it kicks me, I don’t think it’s the world, it might be client-side I’m not sure. (Sorry I didn’t notice someone commented on this bug)

And it still to this day on all version up to 1.21.114 still have this bug going on.

But now the error is switching between “the host connection has been lost” and “multiplayer connection failed please try again later…” ..or something like that

Bug No longer happens, but a new One happens on 1.21.114-1.21.121+ whenever you join a server or lan world it says: “Your client is having trouble establishing a connection to multiplayer services, Please check your internet connection, restart your client, and try again. Multiplayer Connection Failed”
