As mentioned in this link
pls try to swap between, it may help you
By swapping the ports between 7180 (HTTPS) and 7183(HTTP) , cloudera management services fails to start
The fact that your server started on port 7183 does not mean that communication between Agents and Server is over SSL.
If you have enabled the "Use TLS Encryption for Agents" and restarted the cloudera manager server, then you should verify that Cloudera Manager started with SSL and the certificate is correct?
You can do it by :
$ openssl s_client -connect cm.server:7182
Agents connect to the 7182 port.
If you get a certificate as a response then you should check the Certificate Authorities you have configured in Agents' config.
