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?
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:
