I’m feeling so frustrated by this issue that I’ve had for two weeks now. I get the same problem. I have checked my firewall, and I have uninstalled, and re-installed UE4. I’m still getting the same exact problem over and over again, and all the threads I find on this seem to end with the same resounding, NO SOLUTION, … people say, oops it’s working now, and then the issue is dropped. Well for me it is not dropped. I have tried so many of the solutions here.
