when I use the cname and cdn domain,can not get the ssl_expire_earilest_time

[conardchen]

when I use the module http_2xx to get the ssl Certificate expire time，I found my domain use the cdn and cname ,it can not get the probe_ssl_earliest_cert_expiry 。

my blacbox_exporter config: `modules: http_2xx: prober: http http: preferred_ip_protocol: "ip4" http_post_2xx: prober: http http: method: POST tcp_connect: prober: tcp pop3s_banner: prober: tcp tcp: query_response:

• send: "SSH-2.0-blackbox-ssh-check" irc_banner: prober: tcp tcp: query_response:

• send: "USER prober prober prober :prober"
• expect: "PING :([^ ]+)" send: "PONG ${1}"
• expect: "^:[^ ]+ 001" icmp: prober: icmp icmp_ttl5: prober: icmp timeout: 5s icmp: ttl: 5`
