I tried this same scenario and was able to do it successfully. It seems like that might be the error that happens periodically if your internet is not stable. I might suggest trying to exit your browser and try a new instance to see if that works. I know I am giving you the classic IT response of "did you try to restart it?", but it seems to work in another place so I have to believe it is something with your connection or that particular model.
Have you tried doing this in a different model to see if it works there? Sorry, I'm not really providing a real answer, besides that it should work.
