### Website URL [https://www.allahordanbdshop.great-site.net/](https://www.allahordanbdshop.great-site.net/) ### Error Message NET::ERR\_CERT\_COMMON\_NAME\_INVALID ### Other Information My website is hosted on InfinityFree. The www version of my website opens, but the non-www version shows NET::ERR\_CERT\_COMMON\_NAME\_INVALID. The SSL Certificates page says “No SSL certificates found”, although InfinityFree says free subdomains have SSL by default. Please help me fix this SSL certificate issue. ---

_Beep boop, I’m a bot! I dug through the forum to get you started. I sometimes get things wrong though, so do with this what you will until a human has a look._ The error is on the `www` address, not the non-www one. The URL in your post is `https://www.allahordanbdshop.great-site.net/`. An article about free subdomain SSL says `www` is the part that can’t have SSL: > The system-wide SSL certificates can only protect direct subdomains, which means www subdomains are not covered. For example: the domain example.ct.ws is protected with SSL, but www.example.ct.ws cannot be protected. So `https://allahordanbdshop.great-site.net/` (no `www`) should be the one with a valid certificate. `https://www.allahordanbdshop.great-site.net/` will show `NET::ERR_CERT_COMMON_NAME_INVALID`, and nothing on the hosting side can change that. The “No SSL certificates found” message on the SSL Certificates page is expected too. Free subdomains use the system-wide certificate, so nothing gets installed per account, and the article says waiting for it won’t change anything. The fix is to use the non-www address as your website URL. The article suggests redirecting `www` to non-www, so old links still land on the right page. Redirecting from `www` can’t avoid the certificate warning on HTTPS, because the browser checks the certificate before it follows any redirect. The article also says you still need to set your website software’s URL to `https://` and redirect all traffic to HTTPS. Here’s the article: > [@Why SSL doesn't work on www subdomains and other free subdomain SSL issues](https://forum.infinityfree.com/docs?topic=116209): > > All free subdomains support HTTPS by default through a system-wide SSL certificate. This benefits most people since you no longer need to set up and install your own SSL certificate. However, there are some important limitations to understand when configuring your website for HTTPS. The www subdomain does not support SSL The system-wide SSL certificates can only protect direct subdomains, which means www subdomains are not covered. For example: the domain example.ct.ws is protected with SSL, bu… If `https://allahordanbdshop.great-site.net/` without `www` also shows the error for you, tell me exactly what the browser shows. Then it’s a different problem from this one. ---

The bot is absolutely correct. If I visit your site without “www.”, then SSL works just fine. ![image](https://forum-cdn.infinityfree.net/original/3X/b/2/b2e4421531c619d06182952f3957f0bf6d649c3a.png) Sub-subdomains are not officially supported by InfinityFree, and that includes the WWW prefix.
