I’ve run into an odd problem and haven’t been able to find any discussion of it so far. I have a Cesium-based website obtaining imagery from GeoServer. I have a proxy configured in Apache to communicate between my site and GeoServer. On my local installation, everything works fine. When I set up the site on a server we’ll be using for demos, the imagery does not load, but only when using Firefox. It works in IE and Chrome.
I’ve used the Network tab in the FF debugger to inspect the calls to GeoServer. They are returning normally (200). If I navigate to the WMS URL directly, the imagery loads. But the Cesium globe is showing as a blue ball, and the information in the network tab does not display the image. It says “Can’t load image.”
At first I thought it might be CORS issue, but as I understand it, using the proxy should avoid that problem, and (again) it only fails in Firefox. Does anyone have any thoughts or suggestions as to what I should be looking at? Thank you.
