Fix ARK "Joining Failed" / "Connection Timeout"

ARK's "Joining Failed / Connection Timeout" usually means the query port is wrong/blocked, the server is full or restarting, or your mods don't match. Here's how to fix it.

Check the query port

ARK lists and connects via a separate query port (default 27015), not just the game port (7777). If it's blocked, you get a timeout:

7777/udp   game
27015/udp  query (this one feeds the browser & join)

Mods must match

If the server is modded, a mod mismatch causes join failures. Make sure your subscribed mods match the server's — see ARK mods not downloading.

Join directly by IP

The browser is flaky. Use the console to connect straight to the server:

open server-ip:7777
Server restarting?

ARK servers take a while to fully load after a restart/update. A timeout right after a restart often just means it isn't ready yet — wait a few minutes.

Open the query port (27015), match mods, and "open ip:7777" in console — that clears most ARK join timeouts.

FAQ

Frequently asked questions

Why does ARK say "Joining Failed" or "Connection Timeout"?

Usually the query port (27015) is blocked, the server is full or still restarting, or your mods don't match the server. Open the query port, match mods, or join directly by IP.

What is the ARK query port?

A separate UDP port (default 27015) that the server uses for the browser and for joining — distinct from the game port (7777). It must be open or you'll get timeouts.

How do I join an ARK server by IP?

Open the console (Tab/admin console) and type: open server-ip:7777. Direct connect bypasses the unreliable in-game browser.
