Can't connect to realm

Hello, My friends realm is having connection issues on the bedrock edition of minecraft where none of us can connect to it. This issue has been on-going for a day now and we're hoping it was just a Minecraft server issue. The friend who owns the realm can't connect to the realm either. All the people who play on the realm play on xbox 1 while im the only one who plays on windows 10. I will provide an image for the error message.

 

Thank You
