[BUG] Unable to Download from Manga Dex

What broke?

• [x] Downloader
• [ ] Processor
• [ ] Converter
• [ ] Other

Describe the bug When trying to download from MangaDex, I encountered a Runtime Error that I am unable to continue downloading the files. Surprisingly, Mandown claims there are 34 chapters, however, there are clearly 82 chapters to Spy x Family by the time of this writing. Can you take a look into this?

Steps to reproduce If the downloader broke, please include a URL that breaks it.

Additional context Here is the error that I am experiencing:

Let me know if you need more information, thanks!

Hi,

Thank you for opening an issue! However, Mandown only supports English-translated, hosted comics on MangaDex right now. A quick peek at SPY×FAMILY tells me that a bunch of chapters are not available in English:

And for those that are available in English, many aren't available through MangaDex, but are instead hosted on external sites. Mandown isn't able to go through those external sites unless they're added as a separate source. If you click them, you should see that a bunch of them require logins, too.
