There is a second meaning to "private server fixed." In the modding community, "fixed" sometimes refers to a leaked development build of Zenless Zone Zero that was never meant to go public.
In August 2024, a QA build (Quality Assurance) from a Southeast Asian testing center was leaked. This build connects to a local server used by testers. People call it a "private server" because it runs offline. This build is actually "fixed" – it has infinite stamina, all characters unlocked, and god mode.
However:
For most players, this "fixed" build is a novelty, not a replacement for the live game.
As of April 2026, several Zenless Zone Zero (ZZZ) private server projects have seen significant updates and fixes to address previous bugs, particularly regarding character stats and connectivity. The primary project currently active is Yoshunko, a new server emulator released by the Reversed Rooms community in early April 2026. Current Status & Fixes
Version Support: The latest emulator, Yoshunko, currently supports game version 2.5.2.
Stat Accuracy: Previous issues where private server enemy stats differed from official servers have been identified. New community standards require showcases to specify if enemy HP and damage are correctly calibrated.
Connectivity Solutions: A common "fix" for connection issues involves manually updating the list-general.txt file with specific Cloudflare and HoYoVerse domains to ensure the client correctly routes to the private server rather than the official ones. Key Private Server Projects

Tentacle: A client patch specifically used in conjunction with these emulators to bypass official authentication. Technical Setup Overview
To run a modern ZZZ private server (like Yoshunko or HollowPS), the following steps are generally required:
Server Components: You must run both an SDK server and a game server simultaneously.
Configuration: Settings are managed through a gameserver.json file, which is automatically generated upon the first startup.
Client Patching: A specific client patch (such as Tentacle) is required to redirect the game's traffic away from official HoYoVerse servers.
Hardware Requirements: While minimal setups can run locally, enterprise-grade hardware (24-core CPU, 64GB RAM) is recommended for high-performance dedicated hosting.
While there is no "official" private server, the community-driven Zenless Zone Zero
