Splunk HEC post call not working and getting exception: "PKIX path building failed"

[trinatha]

I am getting below exception for send event through a java rest post call

Exception :

      org.springframework.web.client.ResourceAccessException: I/O error on POST request for “https://input-prd-p- 
     f4txzc7qgv77.cloud.splunk.com:8088/services/collector“: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Curl command :

curl -X POST \
   https://input-prd-p-f4txzc7qgv77.cloud.splunk.com:8088/services/collector \
   -H 'Authorization:Splunk 07944f24-c69e-42fc-af3c-14035cddb034' \
   -d '{"event": "Hello, world!", "sourcetype": "main"}'```

But its working from curl command and not working from java code.

Also running into this.  How do I go about debugging this.

Consider that curl and Java are using different trusted certs store. And it seems like Java's one is not trusting Splunk Cloud certs.
One more option could be that java call goes via proxy and the proxy's cert is not trusted

Did you find the solution? I am hitting the same issue.
