Failed to Connect to Realm

After trying to reset the realm and replace it with a different world I get an error when resetting occasionally that says Failed to reset the realm. Please try again later. After this happens I try to replace the world and get a error message that says an error has occurred. If I try to connect to the realm it says Failed to connect to realm. This has happened multiple times. After a few hours it will allow me to reset and replace and again and then eventually if I reset and replace again it breaks. I reset and replace a lot because I have to test certain things out and then re upload after I fix things. Please fix this.....this is absolutely ridiculous and frustrating, especially given that I am paying monthly for this service.
