Java Edition Realm Connectivity Issue

Put the summary of the bug you're having here

What I expected to happen was...:
To join my Realm server

What actually happened was...:

I can't join my Realm server with the "Timed Out".

When I try to join my Realm, connection takes really long and eventually shows the "Timed Out" screen. Sometimes it appears like it has succeeded to connect to the game, but i can't interact with anything because it's not actually connected. 

 

This is the footage of my several tries joining the Realm.
