First off, please forgive the lack of details here. I can’t share the domain this query is about, as it belongs to a customer who wants to stay anonymous.
I use the Plesk control panel and am using the Lets Encrypt Plesk addon to enable https on a few of the domain in my hosting account.
Most of my domain secure very easily using the addon, without a problem.
I just added a Lets Encrypt certificate to 1 domain and received the following message from Google:
Google has detected that the SSL/TLS certificate used on https://mycustomersdomain.com is self-signed, which means that it was issued by your server rather than by a Certificate Authority. Because only Certificate Authorities are considered trusted sources for SSL/TLS certificates, your certificate cannot be trusted by most of the browsers. In addition, a self-signed certificate means that your content is not authenticated, it can be modified, and your user’s data or browsing behaviour can be intercepted by a third party. As a result, many web browsers will block users by displaying a security warning message when your site is accessed. This is done to protect users’ browsing behaviour from being intercepted by a third party, which can happen on sites that are not secure.
The domain is 1 of 5 subdomains of the parent domain.
The first thing I did, following receiving this email, was to restore the default Plesk certificate to the domain, then setup a new Lets Encrypt cetificate on the same domain.
My question is this: How can I see if Google is happy with the new certificate?
Many thanks in advance for any help.
