When grabbing from tv.orange.fr I get the error The underlying connection was closed: An unexpected error occurred on a receive and also The underlying connection was closed: The connection was closed unexpectedly.
Can this be updated please - also the website https://tv.orange.fr/ redirects to https://chaines-tv.orange.fr/
i dont' know what are you using, our siteini (E version) do not use that url https://tv.orange...or the other https://chaines... and works fine(see log)

Can you post your log? may be the problem is something else.
This is what I get (note just tried with webgrab plus version 3.2.2.9 and still the same)
update siteini.pack or download new siteini https://github.com/SilentButeo2/webgrabplus-siteinipack/blob/master/site...
