Hey Ola! You should look into SNI https://en.wikipedia.org/wiki/Server_Name_Indication to see what's happening here.
Try using check_http with the --sni flag e.g.: # ./check_http -H www.tekniskaverken.se -S --sni -C 30,14 OK - Certificate 'www.tekniskaverken.se' will expire on 09/22/2018 23:59. # ./check_http -H www.bixia.se -S --sni -C 30,14 OK - Certificate '*.bixia.se' will expire on 04/24/2018 23:59. # ./check_http -H www.utsikt.se -S --sni -C 30,14 OK - Certificate '*.utsikt.se' will expire on 05/20/2019 23:59. Hope this helps!! Just let us know if you have any other issues :) Take care Gareth From: Help [mailto:help-bounces+gareth.fletcher=onenet.co...@monitoring-plugins.org] On Behalf Of Axén Ola Sent: Tuesday, 11 October 2016 8:21 PM To: help@monitoring-plugins.org Subject: check_https_certificate I have a webserver that hosts three websites. All of them use port 443 and some kind of forwarding. When I test this check I can only get one certificate but I have three of them to different websites.
