Problem downloading from E-hentai/Exhentai

[Master-x01]

App version: v8.4.3-EH

Android Ver: 4.2.2

Two days ago i was using the app to download from Exhentai, the velocity from the internet i was using was very slow and i noticed that the downloaded doujins were incomplete with some missing pags here and there.

That is something it happened to me before but now im trying to download again with a better connetion and i still have the same problem. Worse, some doujins do not even say 'downloaded' because no matter how much i retry to download them, the thing do not download the missing pag and sometimes just create some html in the place of the pag that says 'Invalid Request'.
