Network Requests Fail with Certificate Error (PKIX Path Building Failed)

Some customers may encounter the following error when using features in ProtocaseDesigner that make outgoing network requests:

PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException

This error occurs when Java is unable to validate the SSL certificate presented by the server you're connecting to. ProtocaseDesigner is packaged with its own embedded Java runtime (JRE). This JRE included a bundled certificate store (cacerts) that does not automatically include custom or system-installed certificates.

If your organization uses a custom internal certificate authority (CA) OR intercepts HTTPS traffic (e.g., via a proxy or firewall with SSL inspection), the Java runtime may reject the certificate because it doesn't recognize it as trusted.
