I recently ran into this same problem of others, getting this same frustrating error when I try to login to UE4 launcher :
The solutions are vague and sometimes non-sensical, and yet I have tracked down each one and tried them. The last was to un-install UE4, and then re-install it. This added to my problems exponentially. At least before I could work off-line, but as I fall further behind in engine releases it’s not a good solution. Now, because of my fresh install, I have ZERO working engines, because an install doesn’t actually install the engine. So they were scrubbed from my system, and now I’m left with no working version of UE4. I’m incredibly frustrated.
Another user suggested a vague, restore your system to a previous time it was working. This is a vague and unacceptable answer to this problem. That would mean scrubbing all the software off my system, to possibly, maybe solve this problem. This is not an answer, this is a vague shot in the dark at great expense to me.
We need real solutions, real answers. Is this because of Windows 8.1? Is it because of something else within UE4? I wish people would stop closing this problem out like it is solved, when it is not. Is this because of the firewall?
Further if I hit OK, and then try to login anyway, it insists that I am not connected to the internet. Which I very clearly am… and I turned off my firewall completely to test whether this was a problem.
I have one week left to pull my work together, and I’m completely hosed thanks to this problem and the vague solutions.
i need help. please. help.
