Thank you for the help and resources.
Strange… When I look it up on the Google page you provided me, it says Valid From “Feb 15, 2016” and Valid To “May 15, 2016”. That makes more sense (I remember hearing about each certificate lasting 3 months), but I don’t know what those other expiration dates signified. I can still provide the domain name if it helps further.
I want to revoke the certificate because… (Cue Long Story) When I signed up for the LetsEncrypt certificate on my Windows Server, I did it using ACMESharp. The command I used to specify my URL to LetsEncrypt when signing up was:
New-ACMEIdentifier -Dns example.com -Alias example.com_Alias
But what I didn’t know is that, apparently, I also needed to include the www version of my URL when signing up. Because when the LetsEncrypt certificate was validated, https://example.com worked, but https://www.example.com did not (notice the www).
So I guess I should have done
New-ACMEIdentifier -Dns website.com www.website.com -Alias website.com_Alias www.website.com_Alias
although I’m still not sure if that command will actually work
But anyway, I wanted to revoke my original certificate so that I could try that command.
Another option I might have is creating an entirely new certificate for just the www version of my URL? But I tried that, and the process got stuck on the validation for some reason.
Do you have any suggestions on what I should do?
