SSL Certificate Install Failed - Not Found Error

My SSL certificate for luxetrendboutique.shop has been issued by Let’s Encrypt

but the Install button returns “Not Found” every time. I have tried deleting
and re-ordering multiple times. The CNAME record is correctly set. Please
manually install the certificate for account if0_41893247.

I checked your domain name but I don’t see any issue. The install buttons all work, and the SSL certificate was installed correctly.

Just to be clear: what happened exactly? Did the install button itself return a “Not Found” error? Or did you click the install button but does the installation status say that no certificate was found? Because if it’s the latter, then that’s expected behavior. As the success message says when installing a certificate:

It may take up to 1 hour for it to become active.

So the installation status not changing right away is expected, because certificate installation is not instant.
