Minecraft Realms infinite log in screen

Recently, when I try to log in to Minecraft Realms, it displays the "logging in…" screen forever and doesn't actually log me in. This might be because I'm stuck on top of the nether, but regardless it should be fixed. I can't just teleport myself away or anything because I have no access to the server console and I can't make changes to the world file and then update the realm with it.
