A concise diagnostic flow that builds on 's and 's early suggestions and helps separate client, router/ISP, and server causes.

Start by separating name resolution from transport. Confirm the domain resolves on an affected PC and on a working machine (use nslookup/dig) and compare the IPs. If the resolver answers differ or resolution fails, test a known public DNS (for example Google or Cloudflare) and clear the client DNS cache; see Microsoft for nslookup and clearing the DNS cache and Google/Cloudflare for public resolver setup:

If DNS looks correct, test IP-level connectivity and HTTP(S) behavior: ping the host IP, run a traceroute (tracert on Windows) to find where packets stop, and request just the headers (HEAD) to see HTTP status codes. Windows tracert docs: https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/tracert

If the site loads via a VPN or a phone hotspot but not on the local network, the problem is likely ISP or router-level filtering or an IP-based block. Useful evidence to collect for the site admin or ISP includes the failing nslookup output, tracert output, and any HTTP status codes or browser error messages. Caution: revert temporary DNS/router changes after testing and avoid persistent configuration changes without a backup.

what operating system are you using? Do you currently use a firewall? What version of IE are you using?

Check your HOST file to see if you got any kind of re-direction for the site in question :)
