Why Does My Website Show a 403 Forbidden Error After Deployment?

A 403 Forbidden error after deployment usually means the server can be reached, but it is refusing to serve the requested resource.

That is different from a 404 error. A 404 generally means the requested resource could not be found, while a 403 means the server has received the request but will not allow access.

After a new deployment, common causes include an incorrect document root, missing index file, restrictive permissions, authentication rules, or hosting-specific configuration.

Quick Answer

If your newly deployed website returns 403 Forbidden, check these in order: confirm the domain points to the intended hosting server, confirm the hosting account is serving the correct directory, check that the deployed website contains the expected entry file, check file and directory permissions if your hosting environment exposes them, check whether authentication or access rules are enabled, check whether your server expects an index file, and review server or hosting logs if available.

Do not immediately change every permission setting. First determine whether the server is refusing access because it cannot find a valid entry point or because access has explicitly been restricted.

Why a Server Returns 403

A web server has rules about what visitors are allowed to access. When a request reaches the server, it determines whether the requested resource can be served. A 403 can occur when access is explicitly denied, the directory is not configured to serve files, directory listing is disabled and no index file is available, permissions prevent access, authentication is required, server rules deny the request, or a security layer blocks the request.

The exact cause depends on the hosting environment.

Check the Document Root

One of the first things to verify after deployment is the directory being served by your domain. Your hosting configuration may point the domain to a specific folder. If you uploaded your website to one directory but the server expects files under a different directory, the server may not find the expected entry point.

The exact directory names differ between hosting environments. Check the hosting dashboard or server configuration and confirm that the domain is connected to the folder containing the production website.

Check for an Index File

Many web servers look for an index document when a visitor requests the root of a website. If the server cannot serve the directory and directory listing is disabled, it may return a 403. Check the production output and confirm that the correct entry file is present where the server expects it.

Check File and Directory Permissions

On hosting environments where you control filesystem permissions, verify that the web server can read the files it needs to serve. Do not blindly apply permission commands copied from random tutorials. Permission models vary by operating system, hosting environment, and server configuration. The goal is to allow the web server to read the website files without unnecessarily making everything writable.

Check Authentication

If your website requires authentication, access-control rules may be responsible for the 403. Check whether you recently enabled password protection, authentication middleware, access restrictions, IP restrictions, or server-level security rules. If the 403 occurs only on certain paths, compare those paths with your access-control configuration.

Check Server Configuration

A server configuration file may contain rules that deny access. Depending on the server and hosting environment, configuration can be stored in different places. Examples include web-server configuration files or application-level rules. Do not copy configuration from another hosting platform without understanding what it does.

Check Whether Only One Directory Fails

This is an important diagnostic clue. If the homepage works but a subdirectory returns 403, the problem may be specific to that directory. If the entire domain returns 403, investigate the document root, permissions, hosting configuration, and entry file first.

Check the Hosting Logs

If your hosting provider exposes server logs, check them. A log entry can provide information that the browser's generic 403 page cannot. Look for the request path and the reason the server rejected it. The exact log format depends on the server and hosting provider.

What Not to Do

Do not immediately delete the deployment, change every permission, replace server configuration, change DNS records, or disable security features without understanding them. A 403 is a useful diagnostic signal. Use it to determine what layer is rejecting the request.

A Practical 403 Troubleshooting Order

Use this sequence: confirm the domain reaches the correct server, confirm the domain's document root, confirm the production files exist there, confirm the entry file exists, check readable permissions, check authentication rules, check server access rules, check logs, and test again in a private browser window. This minimizes unnecessary changes.
