Connection problems while using Unreal Engine 4

Hey everyone,

I have been working on a project with UE4 lately and I’ve come across a very annoying thing.

While I’m using UE4, my connection stops working properly. Can’t watch streams or videos while working and I can barely hear my colleague on Discord without lagging. When I close the editor, everything comes back, the lag magically disappears.

Speedtesting while using UE4 does not show any drop or problem what so ever. The launcher isn’t even running, because I’m lauching it directly from my project files (since I thought the client was the issue). No background processes (except for a twitch live or music and my colleague on discord) or updates running.

It is not practical especially when I have to communicate. Someone came across the same issue and solved it ? Or has a workaround for it ?

Thanks in advance.

Bump. Would really help me out if someone has the answer.

I have exactly the same problem.
I installed the Epic Games Launcher
I downloaded the unreal Engine

after installation of the editor, i get packetloss and the connection problem continues as long as the launcher or the editor is running.
I uninstalled everything and installed the launcher again. I have no problems installing a game, playing the game and using the internet normally.

so i tried to download and install the Editor again and after the installation completed, i got the same packetloss problem when either one of the two apps are running.

support still thinks its a computer problem but problem occurs after the editor is installed.
