Connectivity Problem with Minecraft Bedrock - Bedrock server UDP responses not reaching clients

I got a workaround on another thread in case someone can benefit from this. At least we can get 1 working bedrock server.

:star: What “Enable LAN Visibility” actually does

When Enable LAN Visibility = true, the Bedrock server:

1. Starts sending LAN broadcast beacons

These are small UDP packets sent to the client’s IP directly.

2. Switches to a different RakNet handshake path

The LAN handshake is smaller, simpler, and uses different packet sizes.

3. Sends smaller UDP response packets

These packets are below the size threshold that Hostinger is filtering.

4. Does NOT send the full MOTD response packet

The MOTD packet is the one Hostinger was blocking.

So with LAN visibility ON, the server avoids sending the large packet that Hostinger was dropping.

:star: Why this makes your server suddenly work

Your earlier tcpdump showed:

  • Inbound packets: 33 bytes

  • Outbound packets: 33 bytes

But a real Bedrock server should send a ~150 byte response.

Hostinger was blocking that larger packet.

When you enable LAN visibility:

:check_mark: The server stops sending the large MOTD packet

:check_mark: It sends only the small LAN beacon packets

:check_mark: Those packets are small enough to pass through Hostinger’s filtering

:check_mark: Your client receives something, so the connection succeeds

In other words:

LAN mode avoids the packet that Hostinger was blocking.

:star: Why this is NOT a real fix

LAN visibility mode is not designed for internet servers.

It:

  • Reduces compatibility

  • Can break cross‑platform connections

  • May fail for players far away

  • Is not guaranteed to work consistently

  • Is not how Bedrock servers are meant to operate publicly

It’s basically a workaround that works only because Hostinger is filtering the normal packets.

:star: The real underlying issue remains:

Hostinger is still blocking or truncating large outbound UDP packets.

LAN mode just happens to use smaller packets.
