Environment

Release : 12.x.x

Component : Access Gateway

Cause

Access Gateway's Tomcat is a client to backend servers.

The configuration to the CA certificate store is defined in the server.conf as below.

This "ca-bundle.cert" is lacking the certificate chain of the backend server.

Resolution

Obtain the certificate chain of backend HTTPS server in PEM/BASE64 format.

Append the backend certificate chain in to the "ca-bundle.cert" file.

Restart Access Gateway service.
