Questions related to using GeoServer WMS

hello.
I have a question related to using GeoServer WMS.

I am trying to visualize a raster image in GeoServer using CesiumWebMapServiceRasterOverlay.

I followed the questions or tutorials related to this, but there is a blockage.

This is the part where you put the Base URL.

I entered the URL as shown in the picture below, but I get an error.


What part of the URL I put in is wrong?

If I put the URL in a web browser, it will look like the picture below.

Please tell me what part of my url is wrong.

or

I would be grateful if you could let me know the Base Url value for using WMS with GeoServer…

I wrote the question through a translator.
thank you

Your URL looks right, but of course I have no way to actually test it. When you enter a base URL like you did, Cesium for Unreal will construct a request for the “GetCapabilities” service. Something like this: http://localhost:8080/geoserver/Test/wms?request=GetCapabilities&version=1.3.0&service=WMS

If that doesn’t return a valid response (XML, with details of the layers served by your WMS), something is probably wrong with your WMS server.

thank you for the reply.

After taking a hint from the answer and trying again, it turned out to be a GeoServer issue.
