Deploying kafka trigger to Windows Premium app using eventhubs kafka heads gives ssl cert error

I'm getting the following error in my logs when deployed to a windows based Premium function app: `sasl_ssl://hnltestbkend3wepfx-std.servicebus.windows.net:9093/bootstrap: SSL handshake failed: .\ssl\s3_clnt.c:1269: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed` 

Any idea how to fix this?
