<p>It's the wms server that doesn't work. It has (probably) nothing
to to with QGIS. I've tried the activate the wms address directly
in a Firefox browser and it does not return a getcapabilities
document (it doesn't return anything) .</p>
<p>The wmts adress works though.</p>
<p>Both the WMS and the WMTS addresses are correct according to this
http page:

<p>So I conclude, the USGS has a server/network problem. Since
others on the list can get a list of layers using the same http
address with QGIS it's probably a routing problem in the internal
network of USGS.<br>

<div dir="ltr">I use USGS WMS and WMTS layers. At some point in
the recent past the WMS layers stopped working. I am almost sure
they have worked in QGIS V3. I usually use WMTS because of the
speed, but for final publishing, I have seen some cases where a
corresponding WMS layer is higher definition, so I would like to
be able to use it. Also the long timeout while starting the
project is unfortunate and I don't want to delete the WMS layer.
Here is a WMS layer which fails:
<div><br>
</div>
<div><a
href="https://basemap.nationalmap.gov/arcgis/services/USGSTopo/MapServer/WMSServer?request=GetCapabilities&service=WMS"
moz-do-not-send="true">https://basemap.nationalmap.gov/arcgis/services/USGSTopo/MapServer/WMSServer?request=GetCapabilities&service=WMS</a><br>
</div>
<div><br>
</div>
<div>And a corresponding WMTS layer which works:</div>
<div><br>
</div>
<div><a
href="https://basemap.nationalmap.gov/arcgis/rest/services/USGSTopo/MapServer/WMTS/1.0.0/WMTSCapabilities.xml"
moz-do-not-send="true">https://basemap.nationalmap.gov/arcgis/rest/services/USGSTopo/MapServer/WMTS/1.0.0/WMTSCapabilities.xml</a><br>
</div>
<div><br>
</div>
<div>On the failing WMS layer, I have removed it and added it
back. When I test it I get a message saying that a get
capabilities request has failed. I hope someone who might be
able to figure out what is going on can give this URL a try.</div>
