Failed to send agent registration request + Status: 401 Unauthorized


I am running into following issue when I try to monitor my k8s cluster using Appdynamics. I verified that my controller key is correct. Any other reason why I would run into this issue?

Hi @sajo.sam,

I did some digging and found this info.

We can see 401 when there is an issue either in the access key or in the account name

kubectl -n appdynamics create secret generic cluster-agent-secret --from-literal=controller-key="myaccount access key valid"

Can you please check and confirm if the access key you have used to create the secret is same with the access key under Settings#licenses#Account.
If not the same then please pass the same and repeat the steps of creating a secret and create yaml .
