Hytale Multiplayer Not Working – How to Fix

If you can play Hytale single-player without issues, but multiplayer does not work—even with a fast internet connection—this is a common Hytale problem.

By “fast internet,” this means:

• Discord connects normally
• Other online games and apps work fine

Yet, Hytale multiplayer servers or friends’ worlds fail to connect.

Why This Happens

Hytale uses a modern networking technology called QUIC.
While QUIC is very fast, not all network adapters and drivers fully support it yet. Because of this, multiplayer connections can fail even when your internet speed is good.

Confirm If This Is Your Issue

Before changing system settings, confirm the problem:

1. Plug a USB Ethernet adapter into your PC.
2. Connect it directly to your router.
3. Launch Hytale and try multiplayer again.

If multiplayer works instantly, then this guide applies to you.

Optional: Simple Plug-and-Play Alternative

Some fixes below require advanced network changes and may be confusing.

If you want:

• No manual network tweaking
• No QUIC or driver compatibility issues
• Easy setup for friends

A dedicated hosting provider (like Simple Game Hosting) handles these issues automatically. This is optional, but useful if you want zero troubleshooting.

Fix 1: Disable Priority & VLAN on Your Network Adapter

This is one of the most effective fixes.

Steps:

1. Press Windows + R
2. Type ncpa.cpl and press Enter
3. Right-click your active network connection
4. Click Properties
5. Select Configure
6. Go to the Advanced tab
7. Find Priority & VLAN
8. Set the value to Disabled
9. Click OK

Your internet will disconnect briefly and reconnect.
You may need to restart your PC afterward.

Launch Hytale and test multiplayer again.

Fix 2: Disable RSC (Receive Segment Coalescing)

This option may not appear on all systems.

Steps:

1. Open Network Connections again
2. Right-click your active adapter → Properties
3. Click Configure
4. Open the Advanced tab
5. Look for:
   • RSC
   • Receive Segment Coalescing
6. If available, set it to Disabled
7. Click OK

Restart your PC and test multiplayer.

Fix 3: Disable Flow Control (Power Saving Feature)

Flow Control can interfere with QUIC traffic.

Steps:

1. Open Network Adapter Properties
2. Click Configure
3. Go to the Advanced tab
4. Find Flow Control
5. Set it to Disabled
6. Click OK

Your connection may reset briefly. Restart if needed.

Test Hytale multiplayer again.

Fix 4: Advanced Driver Tweaks (Last Resort)

If none of the above work:

• Some Realtek and Intel network drivers require deeper tuning.
• There is no universal setting that works for everyone.
• You must review each advanced network option and disable features related to:
  • Offloading
  • Packet coalescing
  • Power efficiency
  • Advanced traffic prioritization

This step is highly system-specific and should only be attempted if you are comfortable modifying driver settings.

Conclusion:

Hytale multiplayer issues are usually caused by network adapter incompatibility with QUIC, not by slow internet.

Start with:

1. Priority & VLAN
2. RSC
3. Flow Control

These fixes solve the problem for most players.
