Unable to access UI of Apache Jena Fuseki 2 on Windows 10

Question

I'm trying to work with a newly installed local instance of Apache Jena Fuseki v 5.2.0 on Windows 10.

It's successfully installed, and I launch the server from the command line with the most basic configuration possible, like this:

c:\java\apache-jena-fuseki-5.2.0> fuseki-server --loc=L:\data /mydataset

The console replies:

c:\java\apache-jena-fuseki-5.2.0>fuseki-server --loc=L:\data /mydataset
15:15:20 INFO  Server          :: Running in read-only mode for /mydataset

15:15:21 INFO  Server          :: Started 2024/12/12 15:15:21 PST on port 3030

Then, I attempt to access the UI using the URL provided in the Fuseki Quickstart document:

http://localhost:3030//query.html

To which the response is:

HTTP ERROR 400 Ambiguous URI empty segment
URI:    /badURI
STATUS: 400
MESSAGE:    Ambiguous URI empty segment

If I call the default URI, as in http://localhost:3030/:

I get a 404:

HTTP ERROR 404 Not Found
URI:    http://localhost:3030/
STATUS: 404
MESSAGE:    Not Found

So, the server is obviously accessible from my browser (Chrome 131.0.6778.139). If I request http://localhost:3030/$/ping, a current datetime stamp is returned. All of the other admin URLs, documented at https://jena.apache.org/documentation/fuseki2/fuseki-server-protocol.html appear to return a simple text or JSON response. Similarly, a call to: http://localhost:3030/mydataset/query returns:

Service Description: /mydataset/query

So, clearly, the Fuseki server is answering HTTP requests. But for some reason, I cannot raise the GUI, and more importantly, the SPARQL endpoint, which I expect to see.

Might anyone have any insight on why I cannot raise the Fuseki UI?

Many thanks in advance.
