Windows 10: Minecraft Windows 10: Friends cant join the world's I create anymore

This happened pretty recently, within the last two weeksish. Friends can no longer join the world's I make, and I can't join some of theirs. I can join person 1s server, person 3 and 4 can join person 1 and each others, but I cant join person 3 or 4, and no one seems to able to connect to me. I'm not quite sure what the issue is. Any help would be appreciated.

Recovering Minecraft world

I have the microsoft windows 10 version of minecraft and was having trouble joining some friends on the xbox one version. I deleted minecraft and reinstalled it to hopefully be able to join their world, but when i logged back in, my worlds were not there
anymore. I believe that i did not have the world backed up in a file. Is there any way to recover my worlds after deleting and reinstalling?

 

Cant join friend on minecraft.

I have been having trouble joining my friend's world in Minecraft. We are using cross platform. I am using a nintendo switch and they are using windows 10. When I try to join their world, it says "connecting to multiplayer game" but is then followed by
a message saying "unable to connect to world". They can join me on my worlds but I cant join them. We are both connected to different networks. Help!

 

Minecraft: Windows 10 Edition: I can't join my friend's world

Hey there Ashwin, I'm having problems connecting to my friends world. I have a laptop with minecraft windows 10 edition (i got it from buying minecraft) and she has minecraft pocket edition on an ipad mini, the strange thing was that when i was by her house
i had no trouble at all connecting to her world I would just open minecraft win 10, click play, click friends then click on her world but ever since i came back to my house i would click play then friends and I would see her world but when i click it to join
it say locating server and it stays on that screen for long. I've tried closing minecraft and canceling and rejoining but its not helping she even tried inviting me but that didnt work either. Do you have any other solutions?

(sorry for making this so long)
