This seems to be another example of a server that doesn't keep the parameters sent when building out the Service URLs in the Capabilities document.
I opened the XML file created and added the Service parameter to the URL and now it works:
<MI_WMS_MapDefinition version="1.0"
wms_version="1.3.0">
<HTTP GetCapabilities="https://service.pdok.nl/rws/ahn/wms/v1_0?Service=WMS"
GetMap="https://service.pdok.nl/rws/actueel-hoogtebestand-nederland/wms/v1_0?Service=WMS&language=dut&"/>
<Exception format="XML"/>
<SRS OverrideCoordinateOrder="true">EPSG:4326</SRS>
<TokenUrl Url=""/>
<Image bgcolor="16777215"
transparent="true"
format="image/png"/>
<Layer>
<Name>dtm_05m</Name>
<Style/>
<LatLonBoundingBox minx="1.985912"
miny="50.695818"
maxx="7.820625"
maxy="55.707565"/>
<BoundingBox SRS="EPSG:4326"
minx="50.695011"
miny="1.986035"
maxx="55.706159"
maxy="7.819814"/>
</Layer>
</MI_WMS_MapDefinition>
It's this line where I added the text in red:
GetMap="https://service.pdok.nl/rws/actueel-hoogtebestand-nederland/wms/v1_0?Service=WMS&language=dut&"/>
I have attached the table with the fix.

Dear Peter,
These are resp the URL and the servername tht I get on the WMS Server details.
Is it possible that you try to replicate with this URL and see what you get?

Hey Ad
Are you using a Service that comes included in MapInfo Pro?
Can you try to add this to the service URL in the Server dialog: ";Service=WMS". This is for a WMS service. For the other two use "WFS" and "WMTS" respectively.

Many maps are publicly available in the Netherlands as a webservice or as a dataset.
When trying to use a webservice, WMS, WFS, or WMTS results in a message : The service issued the following exception: Missing key SERVICE.
It is not clear where an by whom this meaasge is generateb, but it carries a mapinfo label.
I contacted the provider PDOK.nl a]n thris position is that it looks like a plugin of Mapinf and they refer us to you.
I raised this point before; the funny thing is it has worked; since I try to use this service irregulary I cannot be specifis as to when this stopped,
PDOK.nl van be reached globally; I would extremely grateful if anyone could try to replicate this. Hopefully followed by a solution.
