Cant get in to realm

So basically 4 days ago my realm became completely unacessable, no one could get in, not even my friends. My mom is paying for the realm so me and my friends can enjoy some minecraft together. Its really sad that were paying for this money, but we cant play together,
*Note it was acessable for some time maybe 2-4 hours, and when we then came back next day it didnt work and its been going like this back and forth.
please fix this or tell me how to fix it, because im kinda tired getting this message again and again

Kind regards,
Nikola
