This narrows the problem to DNS.
WHAT IT TELLS YOU
The server is running, your files are present, and the site works. Only the name-to-address mapping is failing.
WHAT TO CHECK
- Is the domain registered and unexpired? Look it up in WHOIS. An expired domain produces exactly this symptom.
- Do the nameservers match the pair for your account? Compare WHOIS against Services > My Services.
- Has enough time passed since a change? Up to 24 hours.
- Does the zone have an A record pointing at the right address? Check cPanel > Zone Editor, or your external DNS provider if that is where records live.
- Are you editing records in the right place? If your nameservers point at Cloudflare, cPanel changes have no effect.
A CAVEAT ON TESTING BY IP
On a shared address, visiting the address directly does not show your site, because the server cannot tell which of its sites you want. This is normal and not a fault. Use a hosts file entry instead, which supplies both the address and the hostname.
