Cannot use https even already finished configure

My domain is:
My web server is (include version): Nginx
The operating system my web server runs on is (include version): Centos 6
My problem is that it also shows the page of Nginx when visit https webpage, and I already check the netcat, 443 port stays on listen state.

I just wanna to know are there some solution to handle the issue.
Thank you.

I already configured the lets encrypt file to Nginx.conf shown in the following sentences.

worker_cpu_affinity auto;

Hi @Yanzziang

loading your domain with my FireFox there is no problem visible.

Checked with - it’s the same.

There are some “not so good things”, your name servers are terrible, there is no redirect http -> https.

But your non-www and your www-version have the correct certificate, Grade B, that’s ok.

Hi JuergenAuer,

Thank you for your kind advice.
I add a redirect from http to https, and made a new configure on host.conf.
It appears working now.

Thank you !
