I'm unable to build the light, how to fix it?

Hi there,
I have posted 2 questions in regarding this problem. no response… I read similar topics and did everything that was recommended.

In my case the engine just freezes at:
Starting up Warm Connection… (100%)

After checking the log I can see that there is a problem with starting a Swarm Coordinator.

"SwarmCoordinator failed to be initialized"

If I start it manually I still can’t establish a connection with the agent.

[Network] Pinging Coordinator…

[Network] Coordinator has failed to respond

  • My firewall is off
  • I have the latest .NET Framework 4.6.1 installed
  • I have tested this on a fresh project and some templates, it just never worked.

Any suggestions or help in resolving this issue would be appreciated.
