What is discord-cdn-fix?

This project is a Windows tool that helps users in Russia access YouTube, Discord, and Telegram when those services are being throttled or blocked by internet providers. Internet service providers in Russia use deep packet inspection (DPI) to identify and slow down traffic bound for certain foreign platforms. This tool works around that by bundling two existing open-source utilities, GoodbyeDPI and Zapret, into a single program that alters network packets in a way that prevents DPI systems from recognizing and restricting the traffic. The README lists three services it claims to restore: YouTube video playback including 4K quality, previews, and comments, Discord voice channels that ordinarily get stuck on a connecting screen, and Telegram connections and downloads without needing an external proxy. The project labels this bundled package Bypass Ultimate and lists the current stable release as version 2.1. To use it, the README says to download the archive from the project's Releases page, extract it to a folder without spaces in the path, and run the appropriate file as a Windows administrator. If sites still do not load correctly afterward, flushing the DNS cache via the ipconfig /flushdns command is recommended. A few stated caveats: antivirus tools often flag this software as a threat because it works at the network packet level and is not digitally signed with a paid certificate. The author says this is a false positive. The tool also does not work alongside a VPN, and any active VPN needs to be turned off first. Only Windows is supported in this release, mobile users are pointed to other projects for similar functionality. The README is written entirely in Russian.
