I had a couple members logged into my realm until we logged off for about an hour. Once returning to the game not a single one of my members, nor I could log into the realm. The Realm admin is unable to reset the realm which results in a failed message, we are unable to replace the realm with a backup, and we are unable to Close the realm. It seems like the issue is particular to this specific realm because we are able to log onto others just fine. 

After about 12 hours the realm allowed us back in, however this is the second time our realm has done this.

Attached are videos to display the issues
