VPN connection and gameplay issues

Minecraft Bedrock commonly has trouble with VPNs for reasons which are not entirely clear.

Make sure all MTU limits are set correctly

A common cause of VPN issues is incorrect, inconsistent or too-large tunnel or link MTUs. You can try testing with smaller MTU sizes and see if the problem goes away.

Reduce maximum MTU in PocketMine-MP itself

If you are not able to alter your VPN MTU sizes, you can try reducing the network.max-mtu-size setting in your pocketmine.yml file. The default setting is 1492 - you may have success with smaller sizes.


While a smaller MTU may fix your connection issues, it also reduces efficiency, which may cause higher bandwidth consumption and higher data usage.
