No More Room in Hell 2 Can't Join Friends — Failed to Join Squad Fix

Find which part of the squad is failing

Before you start

Before changing settings, record each player's platform, displayed version, region, exact error text and whether a same-platform squad works. This makes it possible to isolate a version, account, crossplay or service problem.

Fix 1: Match the game version on every platform

Cross-platform patches can finish downloading at different times. A squad test is valid only when every player is running the same current build.

1. Close NMRIH2 on every device and install all available game updates.
2. Reopen the game and compare the displayed build information where the current client shows it.
3. If one platform has not received the same patch yet, wait for version parity before retrying the cross-platform squad.

Fix 2: Disband and rebuild the squad

A fresh squad removes the old invitation and session state from the next test.

1. Have every player leave, then disband the existing squad completely.
2. Restart the game if the previous invite still appears or immediately fails.
3. Create a new squad and send a fresh invite from the current in-game Social or squad interface. Make sure each player is signed in and visible to friends on their platform.

Fix 3: Check crossplay and privacy permissions

Official launch notes confirm crossplay and also acknowledge a crossplay toggle. Platform privacy controls can restrict multiplayer invitations for one account.

1. In NMRIH2, confirm crossplay is enabled if the current client exposes that option.
2. PS5: Settings → Users and Accounts → Privacy → View and Customise Your Privacy Settings; check Communication and multiplayer, including crossplay game invitations.
3. Xbox: review the account's online safety and privacy settings and allow cross-network multiplayer where the current Xbox interface offers it.
4. For child or managed accounts, ask the family manager to review the multiplayer restriction.

Fix 4: Check the current server and region condition

Hotfix 1.0.4.0 fixed incorrect regional routing and a server-full join error. Those notes establish real service-side causes, so do this check before reinstalling the game.

1. Check the official news and Discord for an active incident or maintenance notice.
2. If the message mentions a full server or the whole squad fails at once, wait 15–30 minutes and create one fresh squad before retrying.
3. Record the attempt time and region if the same error continues; 1.0.4.0 specifically changed regional server routing.

Fix 5: Isolate the affected player

A small test matrix shows whether the failure follows the host, one account, one platform pair or every online session.

1. Ask the affected player to enter multiplayer alone, then try a two-player same-platform squad if possible.
2. Change the squad leader and send one new invite.
3. If only one account or platform pair fails, include that exact combination in the support report.

Fix 6: Remove VPN routing for one invitation test

The official Revelation 0.9 notes documented a known issue where using a VPN while sending or accepting Squad invitations could immediately kick the joining player. The note predates 1.0, so use it as a focused test rather than proof that every current squad error has the same cause.

1. Disconnect the VPN on the inviting and joining devices, then restart NMRIH2.
2. Disband the previous squad and send one fresh invitation without the VPN route.
3. If the test works, record the VPN provider and region before deciding whether to keep it disabled for NMRIH2.

If it does not work

If the same pair cannot join after the six checks, submit the platform combination, version, region, attempt time, squad leader and screenshot through the in-game report path, official Discord, or nmrih2.com/support. Do not unlink accounts or forward ports unless current official support tells you to do so.

Evidence boundary

Official sources confirm crossplay, a crossplay toggle, a previously documented VPN squad-invite issue, 1.0.4.0 regional-routing and server-full fixes, and current platform privacy controls. They do not support a 40% restart success rate, a required third-party account link, peer-to-peer squad networking or fixed port-forwarding instructions for this error.
