I have been trying for days to launch the Shadowlands and/or Dragonflight Clients offline. Initially, I was getting an error saying that it could not reach the .versions and cdn file. I used apache and the host file to spoof this, but now I just get an error called "The CAS system was unable to initiali\e: Unable to initialize CAS from build info file. No active insfo entries. Tact instance creation failed. error (7): not available".
