Xbox live disconnect even though I’m logged in.

While logged on to Xbox live, I cannot invite people, join realms, join people’s games either through the friends tab or invites. I don’t if this has something to do with internet because at an xfinity hotspot that isn’t my home but another, I can do these things with no hassle. But with my internet which runs normally, I cannot do these things. Also, when I open minecraft while not logged in to Xbox live, I see the store instantly. But when I am logged in, the store takes a very long time. When I attempt to invite a person to my world I am greeted with a “Oops! You were disconnected from Xbox live” message, and when I do what it says, it still appears. I have tried logging out and logging in, uninstalling and reinstalling the app, and also accepting invites which I receive from a friend who spammed me with invites like I asked him too. After a couple tries with the third method, I was almost able to connect. Until it said ‘unable to connect to world’. Please fix this as joining games is impossible and I want to play whenever I want, not when I got somewhere else. Below is proof that it won’t work. I cannot send a video due to the fact it is 62.16 mb and not at the least set amount of mb of ten. Thank you for your time and I would like this to be fixed immeadiatly.
