No More Room in Hell 2 Lost Connection to Host — How to Fix

Update to 1.0.4.0, check for a live service incident, then create one fresh session. If only one player disconnects, remove VPN or proxy routing, restart that player's network equipment and test a direct stable connection before changing ports or reinstalling.

Direct answer

  • Hotfix 1.0.4.0 fixed incorrect regional server routing and improved Responder protection for qualifying disconnects.
  • A Reconnect option is documented for crashes during map load; it is not a universal recovery path for every disconnect.
  • The error wording does not prove the game is using a player-hosted peer-to-peer session.

Before you start

Record the platform, displayed 1.0.4.0 build, region, party size, squad leader, disconnect timing and exact message. Note whether the whole squad drops or only one player loses the session.

Fix 1: Update and classify the disconnect

The first split is whether every player is removed, one player drops repeatedly, or the game crashes during map load.

  1. Close the game on every platform, install the current patch and restart each client.
  2. If the game crashed during map load, reopen it and use the documented Reconnect option when offered.
  3. If the Lost Connection to Host message appears during a live session, continue with the service and network checks below.

Fix 2: Check server status and regional routing

The 1.0.4.0 patch fixed cases where players, including some in continental Asia, were routed to the wrong nearby servers.

  1. Check the official news and Discord for an active outage, maintenance window or region-specific report.
  2. Return to the main menu, wait 15–30 minutes during an incident, then create one new session.
  3. If every squad member disconnects together, preserve the time and region for the support report rather than repeatedly changing one player's device.

Fix 3: Rebuild the party and change the squad leader

A clean session helps separate stale party state from a repeatable account or connection issue.

  1. Disband the party completely and return every player to the main menu.
  2. Choose a different squad leader, send fresh invites and test one match.
  3. If possible, compare a same-platform two-player session with the failing cross-platform combination.

Fix 4: Test the affected player's local connection

Use reversible connection checks only when the failure follows one player rather than the whole squad.

  1. Disable VPN, proxy or network-level traffic routing for one test; an official 0.9 known issue specifically linked VPN use with squad-invite kicks.
  2. Restart the modem or router and the affected PC or console.
  3. Use Ethernet or a stronger Wi-Fi connection, then run the platform's network test and retry one fresh session.

Fix 5: Avoid unsupported NAT and port guesses

No current official NMRIH2 source in this guide publishes a required port list or says squad management uses peer-to-peer hosting.

  1. Do not open ports solely because the message contains the word host.
  2. If the platform network test reports a NAT restriction, follow that platform's current support instructions or the game's support response for the exact account and network.

If it does not work

If the disconnect repeats, submit the platform mix, patch, region, session time, squad leader, who disconnected, network type and screenshot through the in-game report path, official Discord, or nmrih2.com/support.

Evidence boundary

Official sources confirm regional server-routing, disconnect-protection, server-stability and map-load reconnect changes. The local network steps are low-risk isolation checks; they are not a claim that every Lost Connection to Host error is caused by the player's router.
