PKIX path buildin failed

Request Type

Bug

Work Environment

Problem Description

Error: javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Steps to Reproduce

1. install cortex
2. edit /etc/cortex/application.conf file
3. uncomment play.http.secret.key="CHANGEME"
4. edit info about elasticsearch:

search {
  # Name of the index
  index = cortex
  # ElasticSearch instance address.
  # For cluster, join address:port with ',': "http://ip1:9200,ip2:9200,ip3:9200"
  uri = "https://ip_address:9200"


  ## Authentication configuration
  user = "elastic"
  password = "pass"

5. add a line (i really need it because thehive and cortex are placed on the same vm)
   http.port=9005
6. start cortex
7. go to http://ip_address:9005
8. you can see error as attached

Possible Solutions

Complementary information

Start with /etc/cortex/application.conf and reproduce startup using the configured HTTPS Elasticsearch URI. Trace the PKIX SSLHandshakeException shown during startup; done means Cortex starts successfully and the web interface is reachable at http://ip_address:9005.
