I, too, am having the same problem using a Surface Pro 4 with Windows 10 (OS Build 10586.122).
I tried repairing the Dish Anywhere program a few times but it still will not work.
I get the following error message in Chrome:
There was a problem connecting to your DVR. (Error 17).
I get the following error message in Edge:
There was a problem connecting to your DVR.. (Error 2).
With Firefox, I get the following error when installing the plugin:
After selecting Allow, it downloads the plugin then I get The add-on downloaded from this site could not be installed because it appears to be corrupt.
