Forced SSL on subdomain? in General Discussion Posted January 7, 2019 Hi, I have a domain that is using SSL. Now I created a subdomain on this domain and created a redirect for it. The master cronjob now throws an error: "empty certificate file! Cannot create ssl-directives". Looking in the virtual host files, I see that there is a file called "29_froxlor_ssl_vhost_[mysubdomain].conf". Since the subdomain is a pure redirection, it should not use SSL. There is no need for it. It seems as if subdomains automatically are marked to use SSL, if the main domain is. Since there is no way to add certificates to the subdomain other than via Let's Encrypt, I think that this is wrong. Or they should be added to the SANs automatically.
