Websocket client can not connect with server by IP adress

In my project, I already config use self signed certificate and also add trust for a custom root ca.
in server's certificate, I registered IP "127.0.0.1" and "localhost" in the field "subjectAltName".
when I test with project on go. client can connect with server by 2 link "wss://127.0.0.1:6868" and "wss://localhost:6868"
But when test with project base on qt websocket, client can not connect with server by link "wss://127.0.0.1:6868". It show error: "The host name did not match any of the valid hosts for this certificate".
client base on qt can connect with server by link "wss://localhost:6868"
