Hi,
respectfully, I think you need to provide useful informations first.
Until now we know that you get "404 - page not found".
This is a standard message.
A similar response comes when you try to access:
Here I´ve tried to get the "nonsense.html" .. that does not exist.
So most probalby is not a technical issue. Maybe even not at the server side.
Maybe you just mis-spelled the URL.
But without knowing what you tried (which URL you tried to access) .. it´s impossible for us to give useful answers.
***
"404 - page ot found" is a standard HTTP error mesage.
Like "overtemperature" on a machine. So without knowing what machine it is .. it´s impossible to help.
