I'm repeatedly receiving HTTP 403 Forbidden errors on websites that use Amazon CloudFront. SoundCloud is currently inaccessible for me even though I'm signed in, and the service itself doesn't appear to be down. What could be causing this, and how can I determine whether my IP, browser, or network has been blocked?

A proxy may change the result, but many datacenter and residential proxy ranges are blocked too, and using one can make security systems more suspicious. It’s better to first rule out a VPN, shared network IP, DNS filtering, browser extensions, or an account/session problem before trying that route.
A CloudFront-hosted site can return 403 when its WAF or another security rule blocks your IP, region, request pattern, cookies, or browser fingerprint. If this is happening across several unrelated sites, check whether it occurs on another network, disable VPN or unusual proxy settings, clear the site’s cookies, and try a normal browser. Avoid repeatedly refreshing, since that can trigger rate limits.
The error by itself isn’t enough to identify the cause. Check the full response headers and error page, then compare the result from a different connection and device. If only your current public IP is affected, contact the specific site’s support team or wait for a temporary block to expire. If you manage the CloudFront distribution, review AWS WAF logs, CloudFront logs, geo restrictions, and origin access rules.
