Hi Jody Thanks for reminding me about this issue. I was able to track it down. It has nothing to do with Geotools but with a wrong schema location in the GetCapabilities response:
xsi:schemaLocation="http://www.opengis.net/wms http://schemas.opengis.net/wms/1.3.0/capabilities_1_3_0.xsd http://www.opengis.net/sld http://schemas.opengis.net/sld/1.1.0/sld_capabilities.xsd http://www.qgis.org/wms http://172.21.5.48/ows/somap?SERVICE=WMS&REQUEST=GetSchemaExtension"; Geotools cannot resolve 172.21.5.48 since it is an internal IP. It just runs in a timeout after 60 seconds. best regards Stefan On Mon, May 31, 2021 at 6:00 AM Jody Garnett <jody.garn...@gmail.com> wrote: > That is interesting Stefan, you are the first to report on this.
