Hello @farhan.ext.
Do you have any additional proxy between the Client and the Server?
As this is one of the most common causes of this problem, you can find in our forum 1 , 2

No Roma, there is no additional proxy.

I abled to register and add slave for this server in PMM but this one is not registering

@farhan.ext, then I would suggest reporting a bug in our Jira for better investigation

@farhan.ext try from the simplest query from your PMM Client to the PMM server

curl  -v -X 'GET' \
  'https://pmmdemo.percona.com/v1/readyz' \
  -H 'accept: application/json'

And replace pmmdemo.percona.com with your server url/ip - this will give us more information about the problem.
