Hi, good news. While simplifying my application in order to show you only the layers and the getFeaureInfo button, I noticed that the getfeatureinfo request was not switching the URL. Although both the local and remote layers are visible the featurinfo queries always the same url. In my case I inserted on every switch of the region also the changed specified featureInfo.url. And now it works. But I don't know how tell the featureInfo two or more urls without my switch of the region (via combobox). It doesn't recognise the changed url without specifying. At least for me I found a solution. Thank you for being so patient. Have a nice weekend Lucia

I cannot comment on your observation that you were able to reach GeoServer instances on remote origins without setting a proxy. I also cannot comment on why no GetFeatureInfo request is fired for your remote WMS. At this point, it would be best if you provided some code, preferably as a minimal example, that shows what you've implemented. Andreas.
