Resolution

In één geval waar dit wordt waargenomen, is er een Nginx-server tussen PowerProtect Data Manager en het K8s-cluster. 

Wijzig de volgende instellingen in het Nginx-configuratiebestand /etc/nginx/default.d/server.conf
proxy_redirect uit;
proxy_buffering uit;

PPDM Kubernetes Cluster Discovery is na deze wijziging in orde.
