Certificate Management Service:I use Mozilla Firefox to access a website that has a certificate installed. Why is the website reported as not secure?

Problem description

After the certificate is installed, the website is reported as normal when I access it by using Google Chrome. However, the same website is reported as not secure when I access it by using Mozilla Firefox.

Cause

A weak encryption algorithm is configured on your server.

Solution

We recommend that you use the encryption suite ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4 and the protocol ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3 for your website server.
