The Log Insight Agents reject self-signed certificate.
For Log Insight Windows Agent, go to C:\ProgramData\VMware\Log Insight Agent\cert.
For Log Insight Linux Agent, go to /var/lib/loginsight-agent/cert.
Some platforms might use nonstandard paths for storing trusted certificates. The Log Insight Agents have an option to configure the path to trusted certificates store by setting the ssl_ca_path=<fullpath> configuration parameter. Replace
<fullpath> with the path to the trusted root certificates bundle file. See Configure the Log Insight Agents SSL Parameters.
