GitHub user AsharSi closed a discussion: Unable to create socket at port 4560

While starting the CloudStack environment, I'm getting an issue after starting
the management server with command
```
mvn -pl :cloud-client-ui jetty:run
```
Here below is the error log details for socket not created
```

I visited http://localhost:8080 and got this response
During the Installation I followed the INSTALL.md guide for setting up the

Any idea what could be causing this issue or how to debug further?
