I have attached log files.
There happens an error to start with, even though i have cleared servers in config(see forum post for setup).

Trying to bootstrap with CarrierPublicationProvider { Converter: AutoByteConverter { }, Transcoder: DefaultTranscoder { } }.

So it fails CarrierPublicationProvider but succeeds with HttpStreamingProvider .
Everything works fine, until i do a failover.

It detects changes in the cluster, but is unable to authenticate after that
