I have a problem after the installation of the Let's Encrypt Wildcard Certificate, maybe someone can help me.
I installed a wildcard certificate generated by
sslforfree.com in cPanel.
The domain is
fluidpower.pro and in the hosting, this is an additional domain.
Certificate works for
fluidpower.pro but it does not work for any subdomain that you created in cPanel.
In the cPanel Certificate Details I see that the certificate is generated for both the subdomains and the domain:
Certificate ID: _wildcard__fluidpower_pro_b5553_5b59f_1560821893_33f836cd985519af6b2aec555b1a5f0d Domains: * .fluidpower.pro fluidpower.pro Issuer: Let's encrypt Key Size: 2,048 bits (b5553b52 ...) Expiration: June 18, 2019 1:38:14 AM
But when I try to go to some subdomain, for example
test.fluidpower.pro I have a mistake
NET :: ERR_CERT_COMMON_NAME_INVALID
I checked in `whynopadlock.com` and found this explanation:
Your SSL certificate does not match your domain name! Protected domains: * .prod.iad2.secureserver.net prod.iad2.secureserver.net
Can anyone explain why it happened? Why does the certificate protect strange domains when running any subdomain, but does it protect the primary domain well? How to solve the problem?
