Elastic prisma cloud integeration

I have single node ELK on prem setup with green health version is 8.15.0. I wanted to add Elastic prisma cloud integeration in it. My fleet is green in health and other integeration run perfectly fine. But i am facing problem while setting Elastic prisma cloud integeration. I have setup my Elastic prisma to sent logs to my ELK machine's syslog but on prisma it says TLS handshake Error. Is there any way to bypass TLS communication on prisma? i am using GoDaddy generated certificates on my ELK machine.

Thanks.
