ARK mod mismatch on join?

Server mod list must exactly match client. Install Steam Workshop mods in same order.

Similar in principle but ASA uses different server software. Check ports in panel for your game.

Quick answer: ARK connection issues: check port 7777 UDP, matching mod list and query port 27015.

If you landed here: ARK shows "Connection failed", "Unable to join" or mod mismatch.
