Winlogbeat setup error: x509 certificate is valid for <ip>, not <same ip>

  ca, docker, elasticsearch

I’m trying to send logs from Winlogbeat to my ELK stack.
I installed my ELK stack with docker and configured TLS on it.
I did everything according to the official guide and it worked for my host.
However, when copying the same winlogbeat directory to my Event Collector server, it did not work (all files are the same including the yml file).
When trying to run the "winlogbeat.exe setup -e" I got the following error: ‘error connecting to elasticsearch at "https://elastic-host:9200" Get "https://elastic-host:9200" Winlogbeat setup error: x509 certificate is valid for elastic-host ip, not elastic-host ip’ (same ips). The CA is already added to the trusted root certificates. Everything is configured the same as on the host, on the host it works, on the server it doesn’t. (the ELK server and the EVC are in the same segment so there shouldn’t be any firewall drops)

My .yml (same file on host and EVC server):
on the host it works without the ssl as well and the traffic is still encrypted due to the TLS that I configured on the docker cluster. So I’m not sure the ssl configuration is needed (but I wanted to include them in case they are needed).
