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.
Your DNS isn’t necessarily the cause. That browser message means the server is showing a certificate Brave doesn’t trust, and the cause could be a missing certificate or one that hasn’t been installed yet. Which step did you get to: did the certificate show as issued in the Free SSL Certificates page, and did you install it on your account afterwards?
The SSL guide says the certificate only works once it has been issued and then installed, either with the automatic install button or by uploading it under SSL/TLS in the control panel. It also says a certificate can take a few minutes to take effect after installation.
This is the guide for getting a free certificate on a custom domain:
Paste the domain into an SSL checker, which the install article recommends for verifying a certificate. It will show whether the server presents a certificate for vanajbg.com or something else. A private browser window will also rule out your browser caching an old certificate.
The install article is here:
If the certificate order failed or is stuck, tell me what status or error the Free SSL Certificates page shows. Also tell me whether the domain uses InfinityFree’s nameservers or someone else’s, such as Cloudflare or your registrar’s.
