problem "network ist unreachable" with 0.21.1

[ToBo]

Hi,


I try to get "gnunet-core v0.21.2 release” to run. But "gnunet-core -s” remains 
empty even after hours. The log is showing some kind of network problem with 
gnunet. The network is otherwise working without any problems. What is the 
problem here?
