Problem to join or create Realms

Ok so, I just buy today the 1 month trial of minecraft realms plus because I want to play with my cousins, I get the 1 month free trial and I want to replace world from one of my local worlds but when I'm trying to upload, the game says "An error occured" and I am having so much trouble for joining my realms and I try to shuttdown the server like 10 times and finally shuttdown and now I want to enable the server again and give me an error just like earlier "an error occured" and now I can't open my realms, replace or anything else I can't do anything because this is giving me so much erros.... what is going on??? I really want to pay for this service but not like this, any fix for this? sorry for my bad english
