[Users] Error starting Jypiterhub server

Hello, I installed ODH Operator on an OpenShift v4.8 and deployed it with the default YAML that comes with the operator just adding the Spark section included in the quick installation, and everything is started correctly, but when I start the basic tutorial and try to spawn a server for Jupyterhub I get this error in the Starting Server window: "Failed to send /hub/api/users/iam#myserver(a)emailserver.com/server" Is there anythig that I have to do before starting the Jupiterhub server? Any support would be appreciated. Thank you, Angel
