The unaux.com and liveblog365.com domain names have shared free domain platforms. If these are temporarily unavailable, this can be a non-specific issue that affects your site but can be a site-wide issue that impacts all sites that host a free domain domain name. A server update, a traffic route between countries, or possibly a block or DDoS action in place can be a reason that contributes to this site-wide issue that will need you to simply wait this issue out.
Local Network and DNS Troubleshooting
When domain appears to be accessible for everyone else but you, this could be a function of ISP-level filtering, caching, and so on. It may be worth testing this website through mobile data versus your home network and seeing if they behave differently. A very quick and easy remedy may be to change your DNS for devices and routers to one of these cloud DNS options such as Cloudflare (1.1.1.1) or Google (8.8.8.8). Make sure to then refresh your DNS cache (by running ipconfig /flushdns in windows) and try again later. Also, try testing if this website loads under http:\ vs https:\ - if http:\ loads and not https:\, this could just be an SSL certificate problem versus a domain failure.
Account-Level Restrictions and Reliability
If the other pages on the shared domain work while yours does not, the issue could be on your end. It could be because the resource limits have been reached, the site is marked for abuse, or a problem like a non-functioning WordPress update. However, the fact that you can still use FTP means you can quickly go ahead and save a backup of your files, securing that your root directory is still housing the index.php or index.html page. Users who demand more uptime and would like to avoid the common issues associated with shared free domains should consider hosting a custom domain like .com instead, hosting the page on Cloudflare.
