Deep Rock Galactic Error Code drg-host: How to Fix It

Q: What does drg-host mean in Deep Rock Galactic?

The drg-host error means your game client lost its connection to the player who was hosting the session. Deep Rock Galactic uses a peer-to-peer system where one player's machine acts as the host, so if that player leaves, disconnects, or experiences a network failure, all other players in the lobby see this error.

Q: Can I fix the drg-host error if the host left the game?

No — if the host intentionally quit or lost their own internet connection, there is nothing you can do to restore that specific session. Simply return to the main menu and join or create a new game. The error will not affect your save data or mission progress in most cases.

Q: Does the drg-host error mean the game's servers are down?

Not necessarily. The drg-host error is usually about the connection between players, not the central game servers. However, if Ghost Ship Games' matchmaking or authentication backend is having an outage, it can contribute to sessions failing. Check the official Deep Rock Galactic social media channels for server status updates.

Q: Why do I keep getting drg-host every time I join someone's game?

If the error happens repeatedly across different hosts, the problem is likely on your end. Common culprits are a strict NAT type, firewall blocking peer-to-peer traffic, a poor Wi-Fi signal, or an unstable ISP connection. Try switching to Ethernet, opening the required ports on your router, and allowing Deep Rock Galactic through your Windows Firewall.

Q: Will I lose my mission progress when I get the drg-host error?

Usually yes — if the error occurs mid-mission, your progress for that run is typically lost since the session data is stored on the host's machine. However, your overall character levels, credits, and unlocks that were saved before the session started are not affected. Some players work around this by hosting their own sessions to have more control over session stability.

Abstract

The Deep Rock Galactic drg-host error means your game has lost its connection to the session host — the player whose machine is running the multiplayer lobby you joined. This typically happens due to the host leaving the game, a network interruption on either side, or a firewall or NAT issue blocking the peer-to-peer connection. In most cases you can get back into a working session within a few minutes by following the steps below.
