GEOTRUST - The certificate not trusted error indicates that the SSL certificate is not signed or approved by a company that the browser trusts. This occurs most often for one of the following reasons:

  • The web site is using a self-signed certificate. Self-signed certificates can be generated for free but they don't provide as much trust as a commercial certificate. You can tell your browser to trust the self-signed certificate or you can buy (or ask the site owner to buy) a trusted SSL certificate from a certificate authority.
  • The web site is using a free SSL Certificate. Free SSL Certificates are issued by a couple of free certificate authorities but their Root Certificate must be manually imported to each browser to get rid of this error.
  • The web site is using a trusted SSL certificate but it is missing a chain/intermediate certificate. Most trusted certificates require that you install at least one other intermediate/chain certificate on the server to link your certificate up to a trusted source.
