Solved Webmeeting: Cluster Manager not available ?¿?

[ls3]

Is it only me with this problem?

General this indicates that there might be a meeting for the URL running but it is no longer permitted to join the meeting. This is a rare case but may occur when our OPS team takes a server offline for maintenance. A possible solution is to end the existing meeting you try to join and rejoin it after (I know this is not the most convenient case, but as said rare)
