I am using the default alert that comes with the Application. I am using the Resilient Integration for Splunk App from Splunkbase.
__main__ - ERROR - Alert action failed to create Resilient incident!
This is the error I find in the Logs.
ERROR sendmodalert - action=resilient STDERR - InsecureRequestWarning)
This is also an error which might be relevant. I have kept the option for verifying certificate as false. If there are other measures to be set in place to override the certificate verification if that is indeed causing the application to fail. Since it is a test environment we don;t have any CA certified certificates.
