This can occur for either of the following reasons:

  • Certificates may not be valid as the reporting server may have been changed
  • The certificate contains an incorrect host name


To resolve this issue, complete the steps below:

1. Remove the existing contents of the agent directory on the server and reinstall the agent RPM
2. Generate the certificate, making sure to use the correct host name: "/opt/Microsoft/scx/bin/tools/scssslconfig –f –h <hostname>"
3. Check the status of the certificate: "openssl x509 -noout -in /etc/opt/microsoft/scx/ssl/scx.pem -subject -issuer -dates"
4. Discover the agent from the console and sign the invalid certificate without SSH
