I want to connect to a subdomain that I acquired externally, but it is not showing up properly. I set the CNAME in the subdomain admin page and the subdomain changed from “pending” to “successful” in the Readdy DNS settings page. However, when I access the subdomain, I get an “ERR_SSL_PROTOCOL_ERROR” message and the site I created in Readdy is not displayed. SSL is configured correctly on both the subdomain and the domain. I do not know what is causing the problem. Is there anything else I should do? Am I doing something wrong? ==Overview== I want to display a site created with Readdy on an external subdomain, but I get an “ERR_SSL_PROTOCOL_ERROR” message. I have applied Readdy's CNAME in the DNS settings on the subdomain side. The subdomain is set to “success” in Readdy's domain settings. - SSL is correctly configured on both the subdomain and the parent domain. The parent domain's DNS cannot be changed because a non-Readdy site is already set up on the parent domain.
