What is a 403 error code?

403 error code

The 403 status code indicates that the server understands the client's request but denies permission. The user's authentication credentials may be valid, but the server still denies access to the resource.

The 403 error is returned for the following reasons:

The user is successfully authenticated with the provided credentials. However, the user cannot read, write, or execute the requested files or URLs.

IP address blocked
If the user's IP address "inherits" a bad "history" from previous users, the server could fantuan database block the IP address.

It could also happen due to too many incorrect login attempts.

Whatever the reason, if the IP address is blocked, the server returns an HTTP 403 response code.

Request blocked by security settings
The request is blocked by security settings, such as firewall rules.

Geo-location restrictions
Users may be unable to access content based on their location due to incorrect CDN configurations. It could also happen due to firewall rules, IP blocking, or region-specific licensing agreements.
