  2. Your certificate has expired. SSL certificates elapse equally a security precaution. How long your certificate lasts tin can vary, simply at some point, you'll demand to renew it or automate the renewal process (some authorities and web hosts enable you to practice this hands).
  3. The certificate comes from a non-trusted source. Just as with self-signed certificates, if browsers tin't verify the authority that generated your certificate, you'll encounter an error.

Remember that every time a user visits a website with an SSL certificate, their browser needs to validate and decrypt it. If in that location are any errors during that process, they'll see a alert.
