SSL certificates can be trusted on a main browser and function correctly but it can still have chain issues. This problem can result in the application failing, especially on mobile devices and other browsers, because the certificate is deemed untrusted.

To identify a chain issue:

  1. In your browser, go to the following SSL Labs page: SSL Server Test.

  2. Enter the Hostname and click Submit.

  3. Once the SSL test is completed, look in the Additional Certificates section. If there is a chain issue it will show Incomplete for Chain issues.

To resolve the chain issue:

Search your Certificate Authority's (CA) website to download their intermediate CA file. This file links all of the trusted CA certificates needed to reach the root certificate. When this Intermediate CA file has been downloaded, you must upload it to the LoadMaster. For more information, refer to the Importing Intermediate Certificates section.

After you upload the intermediate CA file to the LoadMaster, run the SSL server test again.
