There could be various reasons for secure communication failure in an environment.

1.Expired certificates

2.SSL port not enabled

3.Signed certificate is not set

4.Host name mismatch

Solution:

1.If you discover that the certificate is expired ,on the RCA core or satellite servers use the current version of certificate generation utility to create new certificates, new keystore and trust store files.

2.Verify that the correct port is enabled. You can use telnet command for verify the same.

3.Make sure that signed certificate is set.

4.The form of the hostname simple or FQDN must also match.

For example, if you use the certificate generation utility to create certificates using this command:

Cert_mgr create signed –hostname coreserver.rcas.local

You must use the following URL to create the SSL connection:

https://coreserver.rcas.local:SSLport/console

Where SSL port is the SSL port configured on coreserver.rcas.local
