I've manage to build our ELK environment on Ubuntu 20.0.4 (not Docker) and setup Elastiflow, it works great and I followed this guide which also uses self certs, so we just access using https://220.127.116.11:5601 for example.
I've now been asked to use a proper FQDN for it like https://vmnetflow.mydomain.com and the team that looks after our certificates have given me 2 files. Btw I'm not expert at certificates or ELK.
They also gave me the CA cert camydomain.cer
So I copied these 2:
and the ca cert to:
Then edited the Elasticsearch and kibana yml files to point to these. I then restart the services which are successful and then try the url of https://vmnetflow.mydomain.com and it says it can't connect, not page loads at all. If I try using the IP I get the same issue.
I'm not entirely sure what I need do next to check.
My elastiflow config here. I've # out the working self certs (3 lines) so you can see the working ones too.
My Kibana config here
Any ideas would be most welcome, I'm hoping a second pair of eyes might see something if overlooked.
