Unable to monitor kubernetes cluster with checkmk

  1. i do have kubernetes installed on one server
  2. i installed checkmk on other server
  3. i followed your document. but there is no luck. nothing is getting monitored or there is no relation at all.
  4. i put my kubernetes cluster ip but its getting new error in the UI
    “Failed to tech state [504] gateway time-out retrying in 1 second . in case this error persist for more tahn some seconds ,please verify that all processess on the site are running”

I checked on checkmk its up and running. I donot think so your document is very easy. but implementing on my system why it is so hurdle? need some live support
