[mangadex] Fails to download mangas with more than 100 chapters

[HelpSeeker]

I noticed that I'm unable to download mangas with more than 100 chapters. It happens once the chapters start being categorized in pages (e.i. mangadex.org/manga/13318/dagashi-kashi/chapters/1/, mangadex.org/manga/13318/dagashi-kashi/chapters/2/, ...).

This continues until my IP gets blocked for making too many requests.
I tried it with several mangas. Always the same result.

Thanks for reporting this.

Seem like they changed their page URL scheme from
/manga/13318/dagashi-kashi/2/ to
/manga/13318/dagashi-kashi/chapters/2/.
