When the **com.glide.communications.httpclient.verify\_hostname** system property is not set to the secure value of **true**, the hostname and certificate chain presented by remote hosts during a TLS connection initiated from the ServiceNow instance are not validated. Ensure that the **com.glide.communications.httpclient.verify\_hostname** system property is set to the secure value of **true**. ## More information
