[Geotools-gt2-users] Failed to execute request to WMTS

Hello GeoTools community,

I'm new to GeoTools. Currently I'm trying to establish a connection to a WMTS. I followed the instructions in the WMTS — GeoTools 28-SNAPSHOT User Guide. Unfortunately the request to the WMTS failes.

Here are my system information:

GeoTools version 28-SNAPSHOT (built from r175672287370cf2c54eb30f2bbaa04f743835523)
Java version: 17.0.4.1
Operating system: Windows 10 10.0
GeoTools jars on classpath:

I use Maven. My pom.xml is pretty much the one from the quickstart tutorial but of course I added the gt-wmts dependency.

Here is my error message:

Here is my code sample:

public class App {
   public static void main(String[] args) throws ServiceException, IOException {

       System.out.println(GeoTools.getAboutInfo());

       URL url = "">        try {
       url = "" URL("https://gibs.earthdata.nasa.gov/wmts/epsg4326/best/wmts.cgi");
       } catch (MalformedURLException e) {
       // will not happen
       }

       WebMapTileServer wmts = null;
       try {
       wmts = new WebMapTileServer(url);
       } catch (IOException e) {
       // There was an error communicating with the server
       // For example, the server is down
       } catch (ServiceException e) {
       // The server returned a ServiceException (unusual in this case)
       } catch (SAXException e) {
       // Unable to parse the response from the server
       // For example, the capabilities it returned was not valid
       }

       System.out.println(wmts.getCapabilities().getService().getName());
   }
}

I tried different servers. I get a response to a manual request from all of them.

It would be very much appreciated if anyone has a solution or a hint for me.

Thanks in advance,

Daniel
