Connecting an external server

Updated 4 Nov 2026

What it is

Put a server you host somewhere else on the PulsedMC network, for free. You get an address like yourserver.pulsedmc.net, and players can join from our lobby.

Add your server

Go to pulsedmc.net/external, enter a name, your public address and port, and press Add server.

Add the startup flags

Add these to your startup command before -jar, then restart:

Startup flags
-Dminecraft.api.session.host=https://api.pulsedmc.net
-Dminecraft.api.services.host=https://api.minecraftservices.com
-Dminecraft.api.profiles.host=https://api.mojang.com
-Dminecraft.api.auth.host=https://authserver.mojang.com
-Dminecraft.api.account.host=https://api.mojang.com

Keep online-mode=true.

How players join

Players on 1.20.5 or newer use yourserver.pulsedmc.net. Older versions add :25900.

Problems

Players are kicked when joining

Add the startup flags and fully restart.

It does not connect

Check the server says Live on the External Servers page.

We cannot reach your server

Make sure it is running and the port is open.
