Hmm your log contained four offline URLs which were recognized as offline because the pornhub servers responded with:
Code:
HTTP/1.1 404 Not Found
--> This is clearly not a JDownloader issue - it might have been a temporary pornhub issue or these videos really don't exist anymore.
I've sent you the relevant log via PN (password protected) so you can just search for:
Code:
HTTP/1.1 404 Not Found
--> Scroll up a bit and you will see the full URL and can re-check it.
I was only able to check the same video-IDs via pornhub.com (not pornhubpremium.com) and they appear to be online.
