While purchasing SSL certificate, prefer the common name (domain name) with “www” to be the one for which the SSL certificate must be issued in order to prevent the above error message.

Reason 2:

There can be a possibility that the website must be using the accurate SSL certificate but the CA root/chain/intermediate certificate has not been installed. This is a real getting on nerve case as some browsers will give such type of warning while some do not. Internet Explorer will automatically infuse the intermediate certificates in the very first time while the Firefox won’t.


Install SSL certificate properly by following a step by step guide. To make sure that whether the certificate is installed properly or not use an SSL installation checker tool.
