Two things: - sni is a https only thing, but your checks use plain http. I didn't get it to work at all with the -sni option. - the it-knowlegdebase.net domain has IPv6, so check_http uses IPv6. That didn't work for me. Forcing IPv4 using -4 made it work. Is your web server configured to serve the it-knowledebase.net site via IPv6? I would recommend monitoring IPv4 and IPv6 seperately.
