How to Fix Peak Disconnected from Photon Issue

By Daniel Hidalgo | 2025-06-26 08:55:05
Scaling treacherous peaks in Peak, the thrilling co-op adventure from Landfall and Aggro Crab, is an exhilarating experience—until you're suddenly disconnected from your friends due to the frustrating "Disconnected from Photon" error. If you're struggling with this issue, don't worry—this guide will walk you through the best troubleshooting steps to get you back to conquering mountains in no time.

Why Does the "Disconnected from Photon" Error Occur in Peak?


Peak relies on Photon, a multiplayer networking tool for Unity games, to connect players seamlessly. However, connectivity issues can arise due to network conflicts, software restrictions, or compatibility problems. While an official patch hasn’t been released yet, several workarounds have proven effective for many players.

Top Fixes for the "Disconnected from Photon" Error

1. Run Peak as Administrator


Sometimes, system permissions can interfere with online connectivity. Running the game with admin privileges may resolve the issue:
  • Navigate to Peak’s installation folder.
  • Right-click the game’s .exe file and select "Run as administrator."

2. Restart Your PC


A simple restart can clear temporary glitches affecting Photon’s connection. Close Peak, reboot your PC, and try rejoining your friends.

3. Ensure All Players Use the Same Graphics API


Peak allows players to launch the game using DirectX or Vulkan. If you and your friends are using different APIs, it may cause disconnections:


  • Coordinate with your team to select the same Graphics API (Vulkan has reportedly worked better for some players).

4. Try Using a VPN


Network routing issues can disrupt Photon’s connection. If you’re experiencing frequent disconnects:


  • Connect to a VPN (many free options are available).
  • If you're already using a VPN, try disabling it to see if that stabilizes your connection.

5. Verify Game Files (Steam Users)


Corrupted or missing game files can lead to connectivity problems. To verify Peak’s files on Steam:

  • Open Steam > Library.
  • Right-click Peak and select Properties > Installed Files.
  • Click "Verify Integrity of Game Files."
  • Restart the game after the process completes.
  • 6. Check Antivirus & Firewall Settings


    Overly strict security software may block Peak’s connection to Photon servers. To prevent this:


    • Add Peak’s .exe to your antivirus and firewall whitelist.
    • Temporarily disable your firewall to test if it resolves the issue.

    Final Thoughts


    While the "Disconnected from Photon" error can be frustrating, these workarounds should help restore your multiplayer experience in Peak. If the issue persists, keep an eye out for official updates from the developers.
