Hi Andy, Thanks! It seems this is the problem.... (see below) Both are running 4.1.1 How would one diagnose what exactly is going wrong with the routing of the data packets here? ( I don't have root access on the manager machine) I focused so far only on the connection to the meta manager, but looking more careful to the log, it seems that also the local data server cms can not connect to the local manager although both, local manager and data server, run on the same machine... That's the log until the login try, don't know if there is anything else unusual: ++++++ cmsd anon@MANAGER initialization started.

So it seems you found the problem being a routing problem and probably I should focus first to get the local data server process register with the local manager using the hostname of the machine instead of localhost... But how could this be solved....?
