Failed to connect to Swarm

Hi everyone,

I’m new to UE4, and i get (unbuilt objects) warring always. In addition, if i click on Build button i get Failed to connect to Swarm error sometimes the program stops working after showing the error message!

what can i do to fix the problem.

thank you in advance.

Most common issue it the firewall blocking the connection. Make sure it’s not.

Hello JosephAli,

As S-ed mentioned, your firewall could be preventing Swarm Agent from opening. Take a look at our Troubleshooting Lighting Guide to get more tips and helpful steps to get your Swarm Agent to work correctly.

Let me know if you have further questions.
