Im not able to join a realm that i was added to on my own.

if i go through the menu screen of minecraft i get a message saying i cant connect to the server. but if my friend is in the server and i go through my friends list and click join game on my friend it will connect me to the server. so in order for me to play on a realm now i have to wait till another player is on.

info 

1) I play on windows 10

2) i play on a dell laptop with a core i5 8th gen processor

3) my internet provider is through satellite internet (Via Sat)
