Kibana connecting to IPs not FQDN

if i try to connect with

curl -u kibana:password https://10.0.10.70:9200/_xpack?pretty -verbose

Then I get

curl: (51) SSL: certificate subject name (*.domain.com) does not match target host name '10.0.10.70'

I have the Certificate CA stored in /etc/ssl/certs on my Ubuntu server
So yeah same kind of error, so maybe the problem is originating from the Elastic nodes, I have some other problems with them also, so I have another post with my elasticsearch.yml in here

Think that the issue originates there, as I can see from my "_nodes/_all/settings?pretty"
that is says

"transport_address" : "10.0.10.70:9300",
"host" : "10.0.10.70",

those should be the FQDN. Now I just need to figure out why and get it changed.

Best regards
