I believe I’ve already replied to your thread on the Vermintide 2 Steam forums
Will copy my respose below here too:
Thanks for the log! It’s a shot in the dark, but I can see some unusual references around the time you experience the COULDNT_RESOLVE_HOST error.
Can you please try the following:
Ensure you have the latest Steam client updates and Windows updates installed
Disable any Razer Chroma plugins/software
Please let me know if the errors persist after or not.
