The solution is either to set your Public YP settings to "Never" or retrieve a UVOX cipher key (Advanced Tab) through the DNAS. Here is more information.

In addition I believe I have found a bug. After entering that key it doesn't seem to be written to the configuration file or saved in the database. I plan to open a new thread.

Thanks,
