How to join multiplayer

The client’s multiplayer screen takes a WebSocket address, not a Java IP alone. ArchMC’s published address is wss://arch.mc. Heart SMP’s is wss://play.heartsmp.net. A bare hostname without wss:// is incomplete unless the client adds it for you.

Addresses below come from public directory entries or operator documentation. Listing an endpoint is not a successful connection test, a moderation endorsement or a guarantee that it is online now.

Steps

Open the official client for the version the server asks for. ArchMC wants 1.8.8. TuffNET wants 1.12.2. Heart SMP’s wiki wants 26.2 WASM.
Choose Multiplayer, then add the wss:// address from the operator or the directory.
If the server uses a Microsoft or Discord login, that account system belongs to the server. The project site’s own login is email magic link, Discord or Google, and it is for their site tools.
Shared worlds use the worlds directory, not the public server list.

When a friend says “join my world” and the connection fails, read the can’t-connect guide. Handshake timeouts are a different error and have their own page.

Questions

Why does multiplayer fail on my phone?

Confirm the address starts with wss:// and that the version matches. Mobile browsers can also drop the socket when the tab sleeps.

Do I need an account?

Public directory servers differ. Some are open. The project site login is not a Minecraft account and is not a universal server password.
