[HCoop-Help] kinit(v5): Cannot contact any KDC for realm 'HCOOP.NET' while getting initial credentials

[Omry Yadan]

When I try to log into the hcoop from my home machine I get this:


kinit omry at HCOOP.NET

Password for omry at HCOOP.NET:
kinit(v5): Cannot contact any KDC for realm 'HCOOP.NET' while getting 
initial credentials


it used to work for a long time, but something happened a few days ago 
and this started.


any idea?
