Hytale QUIC Handshake Failed or World Not Loading: How to Fix It

If Hytale shows “QUIC handshake failed”, connects slowly or doesn’t load the world, first check that your game and the server are on the same version and that UDP isn’t blocked. If singleplayer works but servers are slow on Windows, your network driver is the usual cause: Intel and Realtek drivers have rare QUIC problems. Hytale’s fix is to switch off adapter features such as Priority & VLAN.

​

Is this your problem?

The network driver issue matches these symptoms, according to Hytale’s support team:

• Your internet is stable and fast (videos play fine).
• Singleplayer worlds load and play normally.
• Connecting to a server or a friend is very slow, and the world doesn’t load.
• A friend may see you move, but you can’t do anything.
• You play on Windows.

​

Step 1: Check the version and the address

If other players can join and only you can’t, the problem is on your side. Continue with step 2.

​

Step 2: Confirm it is your network driver

Connect through an Ethernet USB adapter (any brand) and try the server again. If the problem goes away, your built-in network adapter’s driver is the cause. The issue affects both Wi-Fi and Ethernet, and a driver update to fix it is unlikely.

​

Step 3: Open your network adapter settings

Try the solutions below one at a time and test Hytale after each one. Your internet drops for a moment each time you click OK. You may not need them all.

​

Solution 1: Turn off Priority & VLAN

Set Priority & VLAN to Priority & VLAN Disabled. Click OK, wait for the connection to come back and try the server.

​

Solution 2: Turn off Receive Segment Coalescing

Set Recv. Segment Coalescing (IPv4) and Recv. Segment Coalescing (IPv6) to Disabled. Click OK, wait and try again.

​

Solution 3: Turn off energy saving features

Set each of these to Disabled, click OK, wait and try again:

​

Solution 4: Full driver configuration (last resort)

Your adapter may not have every setting. Skip the ones it doesn’t have. Restart your PC afterwards and test again.

Frequently asked questions

​

What does “QUIC handshake failed” mean in Hytale?

Your game could not finish opening its QUIC connection to the server. Check the version, the address and that UDP isn’t blocked, then try the driver fixes above.

​

Why do I get “connection aborted by peer”?

The connection was closed before you got in. Work through the same checks: version, address and UDP first, then the driver fixes.

​

Can the server owner fix this for me?

If only one player has the problem and singleplayer works for them, the fix is on that player’s PC. If nobody can join, open a ticket and we check the server.

​

Does this happen on Mac or Linux?

Hytale’s support article describes the driver problem on Windows.
