    Dear author,

    I used your plugin to configure SSL Certificate on my website but from some time all my subdomains which doesn’t have SSL certificate are open with https with error (NET::ERR_CERT_COMMON_NAME_INVALID) – for example (ce4big.lifescience.pl or amici.lifescience.pl) always after opened main site first.

    Can you help me with this?

    Hi @napsterion6,

    to secure a subdomain you need to either generate a new certificate for each subdomain or use a wildcard SSL certificate. A wildcard SSL certificate will automatically secure the main domain and all subdomains. A wildcard SSL certificate can be generated by using the Let’s Encrypt DNS verification method.

    Dear @markwolters

    Yes but i don’t want to secure that subdomains. I wondering why browser try to open them with https even they are not secured.

    Hi @napsterion6,

    your site sets an HTTP Strict Transport Security header which will also force subdomains over SSL. Removing this header should make the subdomains available over https://.
