Endpoint object (and certificate name)

I have deployed new director module.The version of icinga is 2.5.3
In the webserver it is asking to provide the endpoint name.Which i am unable to find anywhere.As i read it in some document it should be the URL FQDN but still it doesn’t work for me.
I am attaching the screenshot of the error. I am stuck in the kickstart wizard page.Unable to go ahead without this information.
