Same as others...I was first idle and got disconnected, then when tried to connect it had the wavy bars screen forever until it said connection error, I exited and relaunched, and since then I don't see the little diamond next to "Minecraft Realms" on the starting splash screen and when clicking minecraft realms it say Error 503 Retry Operation
Having the same issue. I was on 2 nights ago. My husband and friends are all able to play without any issues all except for me. When I click on realms in the game menu I get the same error message.
