Have you ensured to check your email and accept the invitation to join the Epic Games Organization on github? You’ll need to do this in order to access the fix. Ensure that you haven’t missed any of the steps in the setup guide. ---

If you go to Github and log in, are you able to access the Unreal Engine dashboard? The commit link is working fine for me, so it’s possible that you have missed a step in your setup. Ensure that you have run through the entire setup guide that I provided. We mark topics as resolved for tracking purposes. As the user, you are more than welcome to come back in and open up a thread at any time when you have new information. ---
