why am I having this error on my browser when I try to access CDM?

Access is denied

@alpertankut,

I would check the Cloudera Manager logs to see if there is a stack trace or informational lines explaining why the access denied was returned.

Also, try a new browser to see if the same problem is occurring in that.
