I created a subdomain ( circularnews.blakebingham.com ) on my website, but the page is not showing. I put a simple “Hello world!” page on the website as well but still nothing, but I tried going to the page on my phone and a Network Advertising Initiative page appears. I know that these pages will appear on subdomains that don’t exist but I know for sure I created it and was able to upload files to it. Does anyone know a solution?
Did you try using a VPN? Did you also tried to use another Web Browser? Did you also tried to use a Public DNS resolver like Cloudflare’s 1.1.1.1 or Google’s DNS??
Also as what I’ve said it could be a problem with your ISP’s DNS cache or just a problem with you local device.
Your site is also working from here, so that clearly means it’s an issue on your end, not on the hosting side (if it was a hosting issue, nobody would be able to access your site). In that case, removing and re-adding domain names is the last thing you should be doing, because that will just make things worse and take longer.
The reasons are explained more in this article, with workarounds:
