Getting error " PKIX path building failed:" while accessing WSO2 URL

Hi All,

We were accessing a third party URL of a WSO2 Identity server ( through Appian’s Integration object to get a OAuth token. And while testing the URL we are receiving the below error.

Error Message:

 Failed to connect to PKIX path building failed: unable to find valid certification path to requested target

Can anyone let me know if you have faced this kind of error before.
