Hey,
NIS on my VPS worked without problems, but today, just after I started my local NCC it suddenly broke.
Error message: something really bad happened: java.util.concurrent.CompletionException: java.lang.IllegalStateException: network boot failed (org.nem.nis.oh d)
When I disable auto-boot by commenting out the private key for my nis, it works.
But I want NIS to auto-boot.
Why does the error occur?
I already have deleted all data and inserted my config file again - no difference.
Okay, got it 
works
