When I'm trying to connect the webhook URL from Postman it works fine, But When I'm trying to connect from my UAT server I'm getting the below error.

I/O error on POST request for "https://xxxxx.webhook.office.com/webhookb2/xx@xxx/IncomingWebhook/3432432434": 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.

I know it's asking for a ca certificate but How Can I download the certificate for the webhook URL when I'm calling the URL from Chrome it's showing "This page isn’t working".

Any help will be highly appreciated
