Adding non conforming wms layers as URL service

[Aardwolf]

I would like to be able to add the services I have been using on desktop to some web applications.

These layers all have the same origin so fixing the issue on one should fix them all.

The service in question is:

https://wms.mapama.gob.es/sig/Biodiversidad/Humedales/wms.aspx

When I try to add this to as a URL item on arc online it gives me the following error:

"Service 'wms' does not exist or is inaccesible."

This service works without any credentials on ArcMap and ArcGIS Pro.

Hi @Aardwolf ,

When I try to add this WMS to ArcGIS Online I receive a 500 level error, indicating that the issue is likely coming from the server side of the request. I would suggest making sure that the domains from the following document (including protocol) are whitelisted on your WMS server as a good starting point.
