Steps to reproduce:

  • Step 1 clicked drop down, selected insurgency sandstorm
  • Step 2 turned on all ports required for port forwarding on router
  • Step 3 waited over 2hrs before I finally checked console to see that it was giving errors (stuck in “Starting” on the UI).

Actions taken to resolve so far: Googled errors, and all it basically gave me was it’s an authentication issue.
