Multiplayer not working

That’s unfortunate. Could you try a Selective Startup to see if anything could be interfering with Steam or Vermintide 2?:

  1. Press the Windows key
  2. Type ‘msconfig’ and select ‘System Configuration’
  3. On the ‘General’ tab, select ‘Selective Startup’
  4. Deselect ‘Load startup Items’
  5. Reboot your PC
  6. Launch Vermintide 2 as normal, and see if the issue(s) persist
