Неверный идентификатор сессии. Invalid session

Yesterday I paid for a Minecraft Realm for the first time and today it turns out Realms does not work for me at all. Every time I go to Realms it declares that I have an invalid session and that I should relaunch the game. I tried not only that but I also tried logging out of the game, restarting my computer, and reinstalling the game but to no avail. Having done an internet search about this problem I found that some other people have this problem but have found no reproducible solution to the problem. Does it turn out I wasted my money paying for a Realm since I can't even play it?
