Failed to retrieve WMS capabilities

[kipbits]

Hi, I found your explorer while looking for Google Earth overlays for global temperature data. I simply want to take some quick screenshots of the globe for the moment, and don't really feel like upgrading to the new Earth -- since I'm sort of trying to cut Google out of my computer these days. A browser app really seems perfect for my purposes, although I'm having a small problem testing out the explorer: NASA Earth Observations and European Centre for Medium-Range Weather Forecast servers both fail to load.

I get the following error:
Failed to retrieve WMS capabilities from https://neowms.sci.gsfc.nasa.gov/wms/wms.
Failed to retrieve WMS capabilities from https://apps.ecmwf.int/wms/?token=public.

here's a screenshot:

Sentinel works fine however, although it doesn't include heat / temperature data...
Why can't i retrieve the NASA Earth or European Weather Forecast server? Is there a simple way to make this work?

This looks like a very cool app! i wish i could get it working for me. Perhaps I might play with it more later, although I have some other stuff holding me up right now...
