Is there a way to allow Swarm through my firewall?

I recently clicked the Build Button on EU4 and since it was the first time I used “Build” I got a password prompt, but I clicked “No” instead of Yes and now every time I click “Build” it says “Build Lighting Failed. Swarm Failed to Kick off”.
Is there a way to get that prompt up again so I can click “YES”?

Hi DW123,

This isn’t a UE4 specific issue so I can’t provide anything more than you need to edit your Firewall settings and add an exception in for SwarmAgent.exe. A simple Google search should provide you with how to add an exception. If you have an administrator that has password protected adding these sorts of exceptions you’ll need to clear that first.
