The API site was updated to use a new certificate:
Subject: CN=Go Daddy Secure Certificate Authority - G2
By default, this certificate is not trusted in java 1.6 and early 1.7 builds, which causes the the agent connection to the API site to terminate due to a certificate validation error. Such java versions were bundled with ASM agent. To address this, please install the latest 1.7 or 1.8 java version available and update the agent to use this java version. To update the java version used by the agent, please update your APMCloudMonitor.bat/sh so that the path to java points to your new Java version. For example (Windows with Java 1.7 shown):
cd /d %~dp0\CloudMon
C:\Progra~1\Java\jdk1.7.0_80\bin\java -jar .\APMCloudMonitor.jar
Then restart the agent. Please reach out to CA Support if any problems persist.
