Persistent unknown bug

I’ve been constantly unable to open Vermintide 2 within the official realm despite trying the following, all while a message “Backend rejected the challenge response.”:

  • Restart steam.
  • Restart my pc and router.
  • Reinstalled steam altogether.
  • Verified cache twice.
  • Checked for any windows updates.
  • Went into the EAC file for “repair.”
  • Remove any existing mods I was previously using.
  • Checked for windows client updates.

Im at my wits end and any help would be greatly appreciated.

We’re looking in to this and will be posting updates to our ‘Known Issues’ article: Known Issues – Fatshark

Thank you for your patience and apologies for the inconvenience,
