SSL configuration optimization

I spent an hour last night to change the VPS monitoring SSL certificate from the original TrustAsia or Symantec personal DV SSL certificate to a letsencrypt free SSL certificate. The reason is Chrome 70 I will no longer trust the Symantec certificate. The Chromium browser I am using can no longer open websites with Symantec certificates. The Symantec personal DV SSL certificate is applied for at Tencent Cloud. In fact, domestic Alibaba Cloud, Qiniu Cloud, Youpai Cloud, etc.

As everyone's awareness of online security increases, and major Internet companies promote the popularization of HTTPS, HTTPS SSL has now basically become the standard for building websites. Thanks to the free SSL certificates provided by Let’s Encrypt, Digicert, TrustAsia, Symantec, etc., the cost of using HTTPS is now negligible whether it is a personal website or a corporate website.
