Match the build
Exit BOMBANANA on all three machines. Finish Steam updates and restart the client before relaunching.
BOMBANANA lobby not working
Follow the list in order. Stop as soon as one change makes all three players visible in the same room.
Create a fresh room
Do not reuse an old code. Have one player host, then try the new room code once.
Try the global browser
The full release includes both a global lobby browser and room codes. If one path fails, test the other.
Change the host
Let a different teammate create the lobby. A successful host change points to the original host or network path.
Remove route modifiers
Temporarily pause VPN, proxy, traffic filter, or gaming accelerator for one controlled test.
Check the firewall prompt
Allow Steam and the game on the active trusted network profile. Reopen the game after changing a rule.
Test another network
Connect the failing player through a phone hotspot for one join attempt. This separates the device from the home router.
Check Steam service state
If every player suddenly fails, inspect Steam service status and retry later rather than rebuilding local settings.
What the result tells you
| Test result | Most useful next focus |
|---|---|
| Fresh code works | Discard the old lobby and continue. |
| Browser works, code fails | Recheck code entry and room creation state. |
| Another host works | Inspect the first host's firewall or network. |
| Hotspot works | Inspect the original router, DNS, or ISP path. |
| No player can connect | Check Steam service state and game announcements. |
Launch context: A June hotfix addressed an earlier lobby networking issue. Current full-release failures still need the layered checks above because they can come from a different cause.
