PEAK is a uniquely intense co-op climbing experience where players brave extreme terrain and unpredictable environments to reach the summit of a mysterious island. While its physics-based gameplay and survival mechanics are already brutal enough, technical connection issues are proving to be just as dangerous, especially when the game suddenly drops players mid-climb. One of the most common and frustrating problems reported by the community is the game not connecting properly or throwing a “Disconnected from Photon” error. This is especially prevalent among users in Russia, where these disruptions are frequent and persistent.

For a multiplayer game that demands real-time coordination and trust between players, getting kicked mid-session not only ruins immersion but often wipes hard-earned progress. If you’ve been running into these disconnects, can’t join friends’ lobbies, or receive the dreaded Photon-related errors, you’re not alone, and this guide will help you understand and resolve the problem completely.

Part 1: Why PEAK Game Isn’t Connecting

From June 17 onward, the official launch date, players worldwide have been reporting a surge in connectivity issues. A recurring pattern quickly emerged: the "Disconnected from Photon" error message during matchmaking, lobby connections, or even idle gameplay. On community forums, players across multiple regions, including the U.S., U.K., and especially Russia, have echoed similar complaints:

• Disconnection when loading into friends’ lobbies
• Unable to reconnect to rooms after being dropped
• Specific Wi-Fi or LAN setups resulting in higher disconnect rates
• Sudden mid-game drops without warning

Photon, the network engine powering PEAK’s multiplayer functionality, acts as the communication bridge between players. If this bridge becomes unstable, whether due to server congestion, ISP issues, or firewall settings, you’ll be kicked without warning. Russian players, in particular, may experience disruptions tied to localized networking restrictions or global IP conflicts.

Furthermore, PEAK’s peer-to-peer style multiplayer makes it more susceptible to individual network instability. Some users report stable sessions one day and repeated crashes the next, suggesting both server-side fluctuations and client-side sensitivities.

Restart Your Router and Use Wired Internet

A poor or overloaded Wi-Fi connection can be the simplest yet most ignored issue. Restarting your router and switching to a LAN cable can greatly improve your game’s consistency.

Steps:

Step 1: Turn off your router and unplug it from the power source.

Step 2: Wait at least 2 minutes to ensure a full reset.

Step 3: Plug the router back in and wait for all indicators to stabilize.

Step 4: Connect your PC to the router using an Ethernet cable.

Step 5: Disable Wi-Fi from your system to ensure it doesn’t switch networks.

Step 6: Relaunch Steam and PEAK, then test online play.

Allow PEAK Through the Firewall and Antivirus

Sometimes Windows Defender or your antivirus software blocks PEAK’s network connection.

Steps:

Step 1: Open the Start Menu and search for "Firewall & network protection".

Step 2: Click on "Allow an app through firewall".

Step 3: Find PEAK in the list (or click “Allow another app” and manually locate it).

Step 4: Check both Private and Public boxes.

Step 5: Do the same for Steam as well.

Step 6: Restart your PC and retry connecting in-game.

Verify Game Files on Steam

Corrupted or missing files can prevent PEAK from connecting to multiplayer features.

Steps:

Step 1: Launch the Steam client.

Step 2: Navigate to your Library and right-click on PEAK.

Step 3: Select “Properties,” then go to the “Installed Files” tab.

Step 4: Click “Verify integrity of game files.”

Step 5: Wait for Steam to scan and fix any broken files.

Step 6: Relaunch the game and attempt to join a co-op session.

Update Network Drivers

Using old drivers is one of the top causes of connectivity failure in modern games.

Steps:

Step 1: Press Win + X and open “Device Manager.”

Step 2: Expand the “Network adapters” section.

Step 3: Right-click your network card (Wi-Fi or Ethernet) and select “Update driver.”

Step 4: Choose “Search automatically for drivers.”

Step 5: If no updates are found, visit your motherboard or laptop’s manufacturer site and download the latest drivers manually.

Step 6: Restart your computer and try connecting again.

Disable Background Applications & Overlays

Running too many background apps like Discord overlays, Xbox Game Bar, or even Chrome tabs can conflict with PEAK’s real-time networking.

Steps:

Step 1: Press Ctrl + Shift + Esc to open Task Manager.

Step 2: Go to the “Processes” tab.

Step 3: End tasks for unnecessary apps, especially browsers, game recorders, or overlays.

Step 4: Disable Discord overlay via Settings → Overlay → Toggle off.

Step 5: Open Steam → Settings → In-Game and turn off “Enable the Steam Overlay.”

Step 6: Relaunch PEAK and test connectivity.

Part 3: PEAK Game Minimum and Recommended System Requirements
