Description This message means that your server certificate is not yet valid. Visitors will be warned that your website may be insecure or not trustworthy. If a visitor uses HTTPS to open your website, he or she may receive an error message.
Background Server certificates increase security on the internet and are used to verify the authenticity of websites. A certificate is issued and verified by an official, trustworthy institution. A certificate cannot be forged. In everyday life, a certificate can be compared to an identity card or a notarized document. Similar to a passport, certificates are also valid for a certain period of time. Thus certificates make it possible to exchange data via secure connections and form an important basis of trust for operators of online shops.
Consequence In the standard settings, most Internet browser are configured so that websites with an expired certificate are not trusted. A website with an expired certificate will generate a warning message whenever it is accessed. Some browsers or plug-ins, depending on their configuration settings, can even block access your website completely.

If visitors to your website receive a warning message, this will have a negative effect on your company's presentation on the internet. If internet browsers do not trust your website, why should your customers trust you? An expired SSL certificate will also have a negative effect on search engine rank. Your company may no longer be listed at the top of a search engine results page, and it may move down the page even further if the problem persists. Visitors may even be alerted in the search results that there is a security issue on your website.

Solution/Tips If Certificate is not yet valid was reported, deactivate the certificate while it is not yet valid. Your website will then not be certified, but at least visitors will not receive a warning message when they open your website. Alternatively, it is possible to use your old certificate while it is still valid. For information on how to renew certificate, please refer to: certificate expired.
