CentOS - Jul 2017 - certificate for www.xxxx.xx has expired ?? (hostname)

Hello,

I found this Morning a Message in my Logs, that is new for me and I never seen 
this before?

Is this a Error in the Certificate System??

The certificate for www.example.at has expired
Datum: 08.07.17 06:31
Von: root <gjn+www at example.at>
An: gjn+www at example.at
 ################# SSL Certificate Warning ################

  Certificate for hostname 'www.example.at', in file (or by nickname):
     /etc/pki/tls/certs/localhost.crt

  The certificate needs to be renewed; this can be done
  using the 'genkey' program.

  Browsers will not be able to correctly connect to this
  web site using SSL until the certificate is renewed.

No, it means that the SSL certificate has expired - they only have a
limited validity and these default certificates are generated at
install time with a 365 day life.

Create a new certificate. 

If you don't use https (which is probably likely if you didn't know
about certificate lifetimes), then you can ignore the warning (although
it will never stop telling you about it). The warning is issued by
/etc/cron.daily/certwatch and you can put 'NOCERTWATCH=yes' in
/etc/sysconfig/httpd to disable the warnings.

It means, as it says, that the certificate for the site has expired. I'm
guessing you purchased a cert, or maybe used LetsEncrypt, which expires
ever 3 months.  You will have to renew the certificate.
