I Updated the MapWinGIS.ocx to 5.2.4, and that cant support WMS Layer?

Hello Everybody~~

Recently, I Updated my MapWindow from version 5.5 to 5.6
and the MapWinGIS.ocx from version 5.1 to 5.2.4

I have a map server that built by Geoserver
My project is used MapWinGIS to load the WMS from this Geoserver
but when I updated my MapWinGIS, my code was the same as the old version(5.1)
when I use WMS Layer load the WMS, there are always white-block in the area.

Does anyone know how to solve this problem?

my code is:

MapWinGIS.WmsLayer wms = new MapWinGIS.WmsLayer(); 
MapWinGIS.Extents ext = new MapWinGIS.Extents();

ext.SetBounds(-180.0, -270.0, 0, 180.0, 90.0, 0);
wms.BoundingBox = ext;
wms.BaseUrl = "http://localhost:8076/geoserver/wms";

wms.Layers = "my:Satellite";
wms.Epsg = 4326;

wms.Format = "image/png";
wms.DoCaching = true;
wms.Styles = "";

this.axMap.AddLayer(wms, true);

I found there is a Geoserver Demo Site for test:
Geoserver Demo Site
Geoserver Demo WMS Site

axMap1.CursorMode = tkCursorMode.cmPan;
axMap1.Projection = tkMapProjection.PROJECTION_WGS84;
axMap1.TileProvider = tkTileProvider.ProviderCustom;

MapWinGIS.WmsLayer wms = new MapWinGIS.WmsLayer();
MapWinGIS.Extents ext = new MapWinGIS.Extents();

double zMin = 0, zMax = 0;
ext.SetBounds(-124.73142200000001, 24.955967, zMin, -66.969849, 49.371735, zMax);
wms.BoundingBox = ext;

wms.BaseUrl = "https://demo.geo-solutions.it/geoserver/topp/wms";

wms.Name = "topp:states";
wms.Layers = "topp:states";
wms.Epsg = 4326;

wms.Format = "image/png";
wms.DoCaching = false;
wms.Styles = "";

axMap1.AddLayer(wms, true);
