Understanding HTTP Status Codes

What Is an HTTP Status Code?

An HTTP status code is a 3-digit number sent by a server to indicate the outcome of a client's request. These codes inform your browser about whether the request was successful, redirected, encountered an error, or denied.

Categories of HTTP Status Codes

1xx – Informational: Request received, continuing process.
2xx – Success: The action was successfully received and accepted.
3xx – Redirection: Further action needs to be taken to complete the request.
4xx – Client Error: The request contains bad syntax or cannot be fulfilled.
5xx – Server Error: The server failed to fulfill a valid request.

Common Causes of Error Code 403

Incorrect File or Folder Permissions

Improper settings in file permissions (especially on Apache or NGINX servers) can cause 403 errors. Files need to be readable by the web server.

IP Address Blocking

Web servers may deny access to certain IP ranges for security or geographic reasons.

Faulty .htaccess File

Misconfigured .htaccess rules can lead to accidental access denial.

Restrictions from Hosting Providers

Your hosting service may restrict certain content or IPs, especially if you're using shared hosting.
