Build Lighting Offline?

Hey can I build the Lighting offline? It gets stuck at 0% offline. But builds online. Is it possible to build offline? Or does my computer take forever cause it is slow?

My pc specs.

Os. Unbuntu 4.04.10 or whatever. 64bit.

Memory. 8GB

Video card. GeForce GTX 550 Ti/PCIe/SSE2

Processor. AMD FX-4100 Quad-Core Processor × 4

P.S. I just started using UE4. :slight_smile:

And how would I go about doing this? Sorry for asking how but i’m on schedule and sadly don’t have much time to spend on this matter, no matter how important it is to me right now. :frowning:

Never mind. I just read it again and noticed how stupid I am. Ignore that comment above. :slight_smile:

Swarm need to be allowed to use network to get access to ‘localhost’ or ‘’.
Make sure You’ve allowed this activity in firewall.

No other network needed.

Okay I tried everything I could. Still won’t work. I even went as far as to turn off the firewall. Any suggestions? Remeber I am using Unbuntu.
