Hi @smutel,

I believe the issue you've got is similar to [ES 7.8 X-Pack not returning whole cert chain root ca, intermediate and server cert](https://discuss.elastic.co/t/es-7-8-x-pack-not-returning-whole-cert-chain-root-ca-intermediate-and-server-cert/243475/3) .  
You need to concatenate all the cert chain in a single pem file, and set `xpack.security.http.ssl.certificate` to it.
