A 403 Error indicating 'Request blocked' is often a permissions issue due to high traffic or misconfiguration, and troubleshooting should include verifying network settings and consulting CloudFront documentation.
When a user reports that PC0 cannot visit the web server and encounters a 403 Error, this typically indicates a permissions issue where the client's request was valid, but the server is refusing action. The error message suggests that the request has been blocked and provides a general cause stating there could be too much traffic or a configuration error.
To troubleshoot this issue, one should verify the network configuration, checking for any IP restrictions, firewall settings, or server permissions that might be preventing access. Additionally, reviewing CloudFront documentation is advised as it may offer specific steps to address the error in a cloud-based environment.
