How to fix Nginx 403 Forbidden error

Straight-to-point answer:

Nginx 403 Forbidden error indicates that the client does not have permission to access the requested resource. Common steps to resolve this problem include:

Expand the answer in detail:

1. Check file or directory permissions:

• Ensure that the requested resource has appropriate file or directory permissions. Typically, the server should have read and execute permissions, while the user should have read permissions only.
• Use the ls -l command to check permissions for files or directories and adjust them as needed using the chmod command.

2. Check the .htaccess file:

• A .htaccess file may contain rules that restrict access. Check if the file exists and make sure it does not contain rules that deny access requests.

3. Check the Nginx configuration file:

• Open the Nginx configuration file (/etc/nginx/nginx.conf or /usr/local/etc/nginx/nginx.conf) and check the following blocks:

 <code>location / { # 允许或拒绝访问的规则}</code>

• Make sure to allow access to the requested resource. If no explicit rejection rules are found, you can try adding allow all; line to allow all requests.

4. Restart Nginx:

• After making any changes, restart Nginx with the following command to apply the changes:

 <code>sudo systemctl restart nginx</code>

5. Other possible solutions:

• Firewall rules: Make sure that the firewall does not block access to the requested resource.
• SELinux settings: If SELinux is enabled, you may need to adjust the settings to allow access to resources.
• Application Problem: If Nginx is just acting as a reverse proxy, the problem may be in the application. Check the application's log for any error messages.
