Thank you
I am getting the same issue
Also, I did relog into the launcher, I don't think I have a premium account, but I've been on the realm plenty of times in the past, and I've been seeing that you need one to log into it. Has this been a recent change to realms???
Now it says that the client is outdated, but I'm in 1.7.10, can realms be in a snapshot???
This isn't resolved, I'm still getting the error
