Why Does Path of Exile 2 Keep Disconnecting? Proven Fixes for the Frustrating “Unexpected Disconnection Occurred” Error

Can You Permanently Fix “Unexpected Disconnection Occurred” in Path of Exile 2? Essential Solutions for a Smooth Gaming Experience

When you encounter the “Unexpected Disconnection Occurred” error in Path of Exile 2, it means your game client has suddenly lost its connection to the realm server. This issue can be triggered by both server-side and client-side problems. Here’s a clear, actionable guide to resolving this disruptive error and regaining a stable connection.

Common Causes

• Misconfigured or unreliable DNS settings
• Server congestion or instability (especially after patches or during peak hours)
• Corrupted game files
• Unstable graphics settings
• Overloaded system resources
• Wi-Fi-related latency or packet loss

Solution 1: Check Server Status and Switch Gateways

• Confirm server status using Down Detector or official @pathofexile Twitter updates.
• At the login screen, try different gateways (e.g., switch from “Amsterdam” to “London” or “Frankfurt”).
• Avoid gateways that consistently cause disconnections.

Solution 2: Switch to a Wired Connection

Wi-Fi can introduce latency and packet loss. Use an Ethernet cable for a more stable connection.

Solution 3: Disable Discord Hardware Acceleration

Hardware acceleration in Discord can cause resource conflicts, especially on lower-end systems or when overlays are enabled.

How to disable:

Open Discord > User Settings (gear icon) > Advanced > Toggle off Hardware Acceleration > Restart Discord.

Also, consider disabling overlays from NVIDIA GeForce Experience, AMD Radeon Software, Steam, or Xbox Game Bar.

Solution 4: Temporarily Disable IPv6

Some ISPs have poor IPv6 support, causing instability.

How to disable:

1. Press Win + R, type ncpa.cpl, OK.
2. Right-click your network adapter then choose Properties.
3. Uncheck “Internet Protocol Version 6 (TCP/IPv6)“, OK.
4. Restart your PC.

Solution 5: Change DNS to Google DNS

Flushing and switching DNS can resolve connection issues.

Flush DNS:

Open Command Prompt as admin, type ipconfig /flushdns, then Enter.

Change DNS:

1. Open network adapter properties > Select “Internet Protocol Version 4 (TCP/IPv4)” > Properties.
2. Use the following DNS addresses:
   • Preferred: 8.8.8.8
   • Alternate: 8.8.4.4
3. Save and restart your PC.

Solution 6: Lower In-Game Graphics Settings

High graphics settings can overload your system, causing stutters or crashes that disrupt server connection.

Suggested settings:

• Renderer: DirectX12
• Display: Dedicated GPU
• Mode: Fullscreen
• VSync: Off
• Dynamic Resolution: Disabled
• Resolution: 1920×1080 (for weaker systems)
• Upscale Mode: NVIDIA DLSS/AMD FSR (if available)
• Texture Quality: High or Medium
• HDR: Off

Solution 7: Verify or Reinstall the Game

First, verify game files:

On Steam: Right-click Path of Exile 2 > Properties > Installed Files > Verify integrity.

If issues persist, reinstall:

Uninstall Path of Exile 2 > Restart PC > Download and reinstall the latest version.

Solution 8: Reset Network Settings

Restores all network configurations to default, clearing problematic settings.

Warning: This will remove saved Wi-Fi networks and VPN profiles.

How to reset:

Press Win + I > Settings > Network & Internet > Advanced network settings > Network reset > Reset now > Restart PC.

If Problems Persist

If none of these solutions work, the issue may be with your ISP or external network routing. Gather a WinMTR trace during disconnections and submit a support ticket to Path of Exile support. Include your selected gateway, IP address (if comfortable), and the trace file. This helps the network team diagnose routing or latency issues beyond your control.

By systematically following these steps, you can significantly reduce or eliminate “Unexpected Disconnection Occurred” errors in Path of Exile 2, ensuring a smoother and more enjoyable gaming experience.
