Why am I getting CloudFront 403 errors on multiple websites?

This could be a web application firewall or CloudFront protection rule blocking your requests. Repeated requests, unusual traffic patterns, or an IP reputation issue can sometimes trigger a 403. Try checking whether the problem occurs on another network or device, then review your browser, VPN, and network settings.

There isn’t enough information to identify the cause yet. The exact error page, response headers, affected domains, your network type, and whether the issue changes with a different connection would help distinguish an AWS WAF rule from a local browser or IP-related problem.

A 403 only tells you that the server or an intermediary refused the request; it doesn’t necessarily mean the entire service is down. Clear site cookies, try a private browsing window, disable extensions temporarily, and test without a VPN or proxy. If it happens everywhere, contact the affected site’s support team with the error details.
