Thank Daniele, I have tried your recommendations, and now works... I had tried hundreds of examples of web services that included the empty fields of the user and password, and they worked perfectly, but from what it seems this service does not support it, thank you very much again

Hello Elena,
the error messages report "Unauthorized".
I would try by modifying the ServerlUrl, removing the user and password empty parameters, so that it just contains the base WMS url:
<ServerUrl>https://wms.mapa.gob.es/sigpac/ows?SERVICE=WMS</ServerUrl>
and also removing the <UserPwd>:</UserPwd> tag at the bottom of your xml.
Let us know if that works.
Regards,
Daniele
