Hello,

Without changing any settings, all domains stopped working when i use domain sample doitauto.de or industriemeister-forum.de I always receive the error message 'NET::ERR_CERT_COMMON_NAME_INVALID.' All domains are using the SSL certificate from the server host. I have now reinstalled Letsencrypt for all domains, but they still use the wrong certificate.
Please help for that i have nor more idea.

Which certificate is selected on the "Hosting Settings" dialog from the SSL certificate drop down?
 
To find out details, please do this:

1) Look into /var/www/vhosts/system/doitauto.de/conf/httpd.conf and find the line "SSLCertificateFile /usr/local/psa/var/certificates/<some filename here>", e.g. SSLCertificateFile /usr/local/psa/var/certificates/certIEA7tc or similar.
# grep "SSLCertificateFile /usr/local/psa/var/certificates" /var/www/vhosts/system/doitauto.de/conf/httpd.conf

2) Check the contents of that certificate by running
# openssl x509 -in /usr/local/psa/var/certificates/<filename from step (1) here> -text
for example
# openssl x509 -in /usr/local/psa/var/certificates/certIEA7tc -text
for the line "Subject CN=...".

What does that line say? Does it say "Subject CN=doitauto.de" or does it say anything different?
 
it say:
Not Before: Jul 31 20:07:07 2023 GMT

Not After : Oct 29 20:07:06 2023 GMT
