Hostname/IP does not match certificate's altnames

Elastic Stack Kibana
1

I have installed ELK 8 stack fresh.

If I change server's IP address, Kibana says: Kibana server is not ready yet.
I looked up in the log file, it says:

Unable to retrieve version information from Elasticsearch nodes. 
Hostname/IP does not match certificate's altnames: IP: 192.168.12.123 is not in the cert's list: ::1, 127.0.0.1, 192.168.12.44, fe80::***

How to resolve this?
I got stuck for 2 days in this problem.
Certificate was created and generated automatically during setup.

That's how TLS works by design so that another server cannot pretend to be you.

If you want to bypass it, you can try configure Kibana with elasticsearch.ssl.verificationMode: certificate. Please do note this is less safe than full which is the default.

Thank you, this worked for me.
