I ran this command:
If i ran a test on ssllabs i will get wrong additional certificates for aubi-plus.ch. It seems like the additional certificate is every time the certificate i registered for aubi-plus.at.
My operating system is (include version):
Ubuntu 16.04.1 LTS
My web server is (include version):
nginx version: nginx/1.10.1
It seems like something is wrong with my fullchain.pem or Nginx automatically serves a second certificate.
Are you just looking at the “No SNI” certificates ?
This is simply the SSL certificate that is obtained if you go to your IP address, without specifying a domain name. You can generally ignore this unless you have clients with very old operating systems / browsers which would require you to have a different IP address for each domain name on https.
