DRM is the technology used by streaming services to prevent unauthorised copying and playback — it usually refuses proxied streams.
Explanation
Netflix, Disney+, Prime Video, HBO Max, and every major paid streaming service use DRM (typically Widevine on browsers, PlayReady on Windows, FairPlay on Apple platforms). The DRM stack verifies the playback environment — signed browser binary, secure hardware path, unmodified OS — before releasing decryption keys for the video. Proxied streams trigger the DRM stack's tamper detection because the network path is unexpected. Result: playback silently fails or drops to low quality. Web proxies cannot defeat DRM — the block is at the client-side DRM check, not at the network. A VPN can pass DRM checks because the browser environment is unchanged; only the network path differs. For DRM streaming, use a VPN, not a proxy.
