My client and some of his website visitors are seeing these errors on Chrome and Firefox “Your connection is not secure/private”.
My client is using MacOS, and so am I but I am not getting the errors he is getting.
If you want the certificate to cover www.solidsurfacecompany.com, you should run certbot again, changing “-d solidsurfacecompany.com” to “-d solidsurfacecompany.com -d www.solidsurfacecompany.com”, make any necessary configuration changes to your web server, and reload or restart it.
I expanded the certificate to include the domain with www. I will have to wait and see what my client says after he tests, I am not aware of any technique to generate the errors myself.
Perhaps in Advanced in Firefox the client could export a copy of the cert and you could post that here (to ensure that it’s the same cert that we’re all seeing)?
The steps in Firefox are Advanced / Add Exception… / Get Certificate / View / Details / Export…
Then the user would choose a name for the .crt file and then send it to you (say, as an e-mail attachment).
If the user’s browser isn’t accepting the cert, it’s also possible that there’s something unusual about the browser or OS rather than something wrong with the cert.
