The ARK: Survival Evolved HostConnection error means your game client failed to establish or maintain a connection to the host session or server you are trying to join. This can happen when joining a dedicated server, an unofficial server, or a friend's hosted session. The issue is typically caused by network instability, server-side problems, firewall restrictions, or outdated game files rather than a hardware fault.

  1. Check Server Status and Your Internet Connection

  2. Restart ARK and Your Platform

  3. Verify Game File Integrity (PC/Steam)

  4. Check and Open Required Network Ports

    Do not expose ports unnecessarily on your router. Only open the specific ports listed above and only while hosting ARK sessions.

  5. Disable or Configure Your Firewall and Antivirus

When to Call a Professional

If you have completed all steps above and the HostConnection error persists, the problem is most likely on the server side rather than your end — contact the server administrator or hosting provider. If you are using a managed hosting service (Nitrado, G-Portal, etc.), open a support ticket with them directly. For console players who cannot resolve the issue after network troubleshooting, contact PlayStation Support or Xbox Support to rule out account-level network restrictions. If your internet service itself appears unstable across multiple tests, contact your ISP for a line quality check.

Frequently Asked Questions

What does the ARK HostConnection error mean?
The HostConnection error in ARK: Survival Evolved or ARK: Survival Ascended means your game could not connect to or communicate with the server or host session you attempted to join. It is a network-level failure — either the server is offline, your network is blocking the connection, your game files are outdated, or required ports are closed.
Why do I keep getting HostConnection error on ARK even with good internet?
Good general internet speed does not guarantee ARK will connect. The HostConnection error can still occur if specific UDP ports (7777, 7778, 27015) are blocked by your router or firewall, if your game version does not match the server's version, if the server itself is down, or if Windows Firewall is blocking ARK's executable. Work through the firewall, port, and game file verification steps.
How do I fix ARK HostConnection error on Xbox or PS5?
On console, start by restarting your router and console fully. Make sure your console's NAT type is Open (Type 1/Open) — a Moderate or Strict NAT will prevent connections to many servers. You can check NAT type in your console's network settings. If NAT is not Open, enable UPnP on your router or set up port forwarding for UDP 7777 and 7778. Also verify that ARK has the latest update installed and that PSN or Xbox Live services are not experiencing outages.
Can a VPN fix or cause the ARK HostConnection error?
A VPN can both cause and fix this error depending on the situation. If you are currently using a VPN, try disabling it — many VPNs block or reroute UDP traffic in ways that break game server connections. In some cases, if your ISP is throttling gaming traffic, a gaming-optimized VPN (such as Mudfish or ExitLag) can actually improve connectivity. Test with VPN off first before trying one.
Is the ARK HostConnection error caused by a server ban?
It is possible. If you are banned from a specific server, you may receive a connection error rather than an explicit ban message on some server configurations. If you can connect to other ARK servers without issue but always fail on one specific server, contact that server's admin to check your ban status. A HostConnection error during connection to official servers is not typically ban-related — it is almost always network or file related.
