Rebooting the Epic Launcher and restarting my Unreal project fixed the issue for me.

Hi,

I have been ripping my hair out of my head with this same issue. I have tried everything from rebooting, to allowing blocked apps through firewall.

I do not how to repair this issue, but one thing I did realize that this is a project related issue. I opened a different project on the same engine version and badaboom the plugin worked again.

Sadly this means I need to start over my project. I am not sure if I should try to migrate some stuff, like maps from the faulty project or just start fresh.

Hopes this helps anyone else banging their to a wall with this issue. It sure almost drove me crazy.
