All multiplayer is broken

I cannot join realms as it stops halfway through the loading bar and won't progress even if I wait for ages.

I cannot even access servers.

I cant join multiplayer worlds.

I cannot be joined either as it days multiplayer hosting has stopped.

This issue was earlier only a problem with me joining friends, now it has gotten worse to all multiplayer access being removed.

My internet is not the problem as I have done multiple network checks inbetween joining attempts. I am also able to play literally anything else without any lag at all.
