Host key verification failed.

What can we do here ? Using the same key that we´re given in the issue. We´ve changed nothing on our end and now it doesn´t work.

@ironpeak Væri hægt að fá svar við þessu sem fyrst? Bókstaflega það eina sem við eigum eftir og heldur okkur frá því að klára verkefnið.

Kubernetes clusterinn er ekki keyrandi og þurfum að komast inn til að laga það.

ssh-keygen -f "/home/isard/.ssh/known_hosts" -R "testerlecroissant.hgopteam.com"
