Unable to start Grizzly http server

I am getting below error when I try starting Grizzly server from Java code. Please help.

javax.ws.rs.ProcessingException: Failed to start Grizzly HTTP server: Cannot assign requested address: bind at org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory.createHttpServer(GrizzlyHttpServerFactory.java:299) at org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory.createHttpServer(GrizzlyHttpServerFactory.java:119) at org.alm.TestClient.setUp(TestClient.java:40) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.testng.internal.MethodInvocationHelper.invokeMethod(MethodInvocationHelper.java:80) at org.testng.internal.Invoker.invokeConfigurationMethod(Invoker.java:525) at org.testng.internal.Invoker.invokeConfigurations(Invoker.java:202) at org.testng.internal.Invoker.invokeConfigurations(Invoker.java:130) at

Code 

@BeforeClass
    public void setUp() throws Exception
    {
        final ResourceConfig rc = new ResourceConfig(AlmApiStub.class);
        System.out.println(config.host()+config.port());
        server = GrizzlyHttpServerFactory.createHttpServer(
                URI.create(String.format("https://%s:%s/", config.host(), config.port())), rc);
    }

I just experienced this error but for a different reason: DNS.

TLDR: verify your host maps to your machine.

I configured my service to run using www.sample.com [use your hostname] but it was mapped to a different machine's IP address. While I had mapped it in the host file it wasn't being honored. That is a mystery for a different day. When I changed the hostname to test.sample.com and verified it mapped to localhost I was able to bind to the address:port I wanted.

Make sure, there aren't any application running on same machine, using same port i.e. 8443. Because Grizzly would be trying to acquire same port, but it might be held-up by another application on same machine. Alternatively, you could try assigning different port.
