If the DNS for a domain cannot resolve to a server, then HTTP service cannot response with a status code. As a result, you get no response and no HTTP status code.
Why and How To Fix No HTTP Status Code
If you are experiencing this issue, then one of the following is happening:
- The server is down. – If the server is down, then of course you would not get a response from the HTTP service on the server.
- You misspelled the domain name. – Check to make sure the domain you are attempting to access is spelled correctly, and then try again.
- The domain name is no longer registered. – The domain could have expired and the owner decided to not renew the domain name. In this case, the domain does not exist. You can verify this by checking the WHOIS information or checking the see if the domain is available to register.
