ssl certificate key error

Question

I want to run a https node.js server with websocket in centos 7 server. It runs without any error but in browser console I get this error :
NET:ERR_CERT_AUTHORITY_INVALID
It works without error locally by http
but when I want to connect it on server by wss connection can't be stablished
I also created 2 self-signed crt keys but the errors are still showing

Answer 1

It was because I was using IP instead of domain. The keys was compatible with specific domain, thanks

Answer 2

//Maybe it's because you are using duplicate keys, Key Which has been already used
