Can't Get On Realms But Friends Can

I recently got a new realm, I had a older realm but didn't renew it in time, so I bought a new realm and downloaded the old realm and put it on the new one. I try to join the realm but it says Unable to connect to realm, I've tried everything to solve this but nothing works. I have tried on both pc and Xbox but both don't work. UPDATE, I found a way to get into my realm, you need a friend to join the realm and invite you to it.
