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.

Thanks,
