You can become a technical or non-technical person about server or web. You can see the error messaging “404 that’s an error the requested url was not found on this server that’s all we know”. I have faced same problem recently.
How You Might See the 404 Error
“404 Not Found”
“The requested URL [URL] was not found on this server.”
“Error 404 Not Found”
“404 File or Directory Not Found”
“HTTP 404 Not Found”
“404 Page Not Found”
Now I am discussion about the title error that is showing “404 that’s an error the requested url was not found on this server that’s all we know”.
I have solved the problem in the following way. Follow the steps:
-> Login your domain control panel
-> Go to nameserver section, you will find four or more text field for inputting nameserver host name.
-> Login your domain control panel and find the nameserver. Most probably it stays at the left sidebar of cpanel.
-> Copy the hostname server and paste it into the domain control panel and save it.
It could take 0-24 hours to update. My nameserver updated in 10 munites. So don’t worry if it takes more time!!!
Hope your problem is now solved.
