I have a server Centos7 Apache2.4 in GCP, deploying several web applications, mostly creating the SSL certificate works correctly, however, a single site does not work.
The creation of the certificate for this site and the redirection http to https works correctly, as well as in the other sites, but at the moment of us validating with a navigator the message “NET :: ERR_CERT_AUTHORITY_INVALID” or "Your connection with this site does not appear it is safe "; Validating the certificate of this site shows the name of the machine and not the domain.
I have reviewed the configuration, comparing it with the other sites where it works correctly, and these are the same.
I have made many requests to Letsencrypt, which generates the error “Error when creating a new order: too many certificates already issued for the exact set of domains.”
What could be the problem?
