We are currently running version 6.0up97.xxxx.6335 2012-06-22 b6335
Should be the latest version available at the moment.
After I recreated the replication task I also start it.
After which I will then try to add it to the failover task.
At that point you get the 'disconnected' error message.
Funny thing is though. I just tried it again and it got accepted.
You just need to wait a few hours before it works, apparently...
