Total _newbie_ here!

Trying to run the Docker Desktop tutorial _welcome-to-docker._

The logs display:

```auto
2023-10-25 08:09:10 INFO Accepting connections at http://localhost:3000
2023-10-25 08:18:20 
2023-10-25 08:18:20 INFO Gracefully shutting down. Please wait...
2023-10-25 08:18:21 INFO Accepting connections at http://localhost:3000

```

but when I try to connect to [http://localhost:3000](http://localhost:3000) I get similar messages in Chrome and Firefox:

```auto
Unable to connect
Firefox can’t establish a connection to the server at localhost:3000.

```

My due diligence tells me that no proxy or firewall is active. Of course, I’ve tried the localhost IPv4 address too.

Perhaps, I have overlooked something in the tutorial. Would appreciate indulgence and guidance from someone more experienced, please. Thanks.

Regards.
