@NightHawk007 do you have Manual Throttle|Delay per chapter active? I am at Chapter 600 on both with 4 Max web pages to fetch simultaneously and 3 Manual Throttle|Delay per chapter.

[gamebeaker]

I was able to download both without a problem (Besides one image res. warning for absolute resonance and the two valid xhtml for shadow slave).

@gamebeaker I tired the settings you mentioned, 4 Max web pages and 3 Manual it also stopped after reaching 400 something chapters. After that i tried again with 4 Max web pages and 5sec Manual and it worked and got the full chapters. Thank you for pointing it out.

This error

TypeError: Failed to fetch

Usually means there are network connectivity problems.
Specifically, this is the error message that the browser gives WebToEpub when WebToEpub requests a page (chapter) and NOTHING comes back.

There's really nothing I can do to fix these.

I just pinged https://novelfull.net/ and got a "Site Down" response.

@dteviot as an idea maybe select a value for Manual Throttle|Delay per chapter in the "default" configuration meaning if someone installs the extension for the first time. The reason is that a lot of sites have a cloudflare protection or something similar. I also know a few pages that if your ip gets on a blocklist they don't send a 4xx code but an empty document. And to get unblocked you have to wait.
If you want to implement it i would set 1 sec/chapter as default.
