What's the full error text it gives you? Also maybe try cyotek webcopy too since httrack hasn't been updated in a while.
Data Hoarder
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
It shows this:
MIRROR ERROR! HTTrack has detected that the current mirror is empty. If it was an update, the previous mirror has been restored. Reason: the first page(s) either culd not be found, or a problem occured. => Ensure that the website still existsand/or check your proxy settings! <=
I tried using other tools but haven't had any luck. Cyotek's Webcopy doesn't go deep enough into the site's layers. Or at least I couldn't make it do it.
The solution is here. The site maybe wrongly redirecting httrack because of its default user agent so change httrack's browser id/identity. Did you check the webcopy log for errors, it may be site blocking the app and if that is the case, you will also get the same issue with httrack.
I already read this whole forum thread and nothing in there worked. If you can, please try to download the site and tell me if it works and exactly what you did, because I tried everything I read on that thread and nothing worked. As I said above, I read many threads and many forums and tried everything I found.
I just tried Teleport VLX but the free version is too limited to download the whole site (plus it dumps every file on the same folder, making it extremely disorganised).
Well, it seems I'll really have to download everything manually. Better get started then...
