Endpoint Protection Endpoint Detection and Response Advanced Threat Protection Platform

Issue/Introduction

When attempting to authenticate to the Endpoint Protection Manager (SEPM) REST API, you receive an error, " PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target."  If using Advanced Threat Protection (ATP), you may receive a "non 200 HTTP response" error when establishing the SEPM Controller connection.

Cause

This can occur if the SEPM's certificate was improperly replaced in the Apache folder without utilizing the SEPM wizard.  (server.crt in /apache/conf/ssl) The SEPM server utilizes both a Java Keystore (JKS) for Tomcat and PEM encoded certificate within Apache.  When replacing the SEPM certificate, both of these need to be updated. 

Resolution

Use the Manage Server Certificate option within the SEPM to update the certificate.  See, Updating or restoring a server certificate

Note:  When you replace the certificate on the SEPM, clients may lose connectivity to the SEPM.  See, Best practices for updating server certificates and maintaining the client-server connection, for more information.
