You might receive the message "Cannot establish trust relationship for the SSL/TLS secure channel when upgrading security certificates for vCloud Automation Center."

Problem

If a certificate issue occurs with vcac-config.exe when upgrading a security certificate, you might see the following message:

The underlying connection was closed: Could not establish trust relationship 
for the SSL/TLS secure channel

You can find more information about the cause of the issue by using the following procedure.

Procedure

  1. Open vcac-config.exe.config in a text editor, and locate the repository address:

    <add key="repositoryAddress" value="https://IaaS-address:443/repository/" />

  2. Open Internet Explorer to the address.
  3. Continue through any error messages about certificate trust issues.
  4. Obtain a security report from Internet Explorer, and use it to troubleshoot why the certificate is not trusted.

Results

If problems persist, repeat the procedure by browsing with the address that needs to be registered, the Endpoint address that you used to register with vcac-config.exe.
