Reasons for the error

[sumaiyakhatun26]

The 404 not found error occurs for a number of reasons.

An incorrect address or link that leads to a non-existent page. In particular, the user may make a typo when entering it into the search bar. If the domain is written correctly, a notification will appear on the screen that the page was not found. If the name is specified incorrectly, the site will not even open.
Broken link (an inactive URL that leads nowhere). Sometimes, when internally linking, qatar rcs data developers forget to remove paths to remote sites.
A page removed from the server. Sometimes the link to the page remains in the browser bookmarks or on third-party resources (for example, forums, etc.). If the user tries to use such an address, a 404 server error message will appear on the screen.
