问题
We have an application hosted on intranet and we are trying to configure Azure SSO for the same. The login page is getting redirected to Microsoft login portal and we are receiving the authorization Code. But when we try to post a request back to Microsoft to gain the token, we get this particular error.

We have placed the certificates by downloading them from the browser and importing them into jdk/jre/lib/security/cacerts as well. Web proxy has been enabled to access internet. We are running out of ideas to get a resolution. Any help would be appreciated.
