Hi! I see you're having trouble with WebNovel showing a 404 error whenever you try to open books. Let's work through this together.

To clarify, does this 404 error appear only on certain books or on all books you try to open? Also, are you using the WebNovel website on your Android 15 device's WebKit browser, right?

In the meantime, here are some steps to try on your device/browser:

1. Clear your browser cache and cookies for WebNovel. Sometimes, old files cause loading problems.
- On your Android 15 WebKit browser, go to Settings > Privacy > Clear browsing data > select Cached images and files + Cookies > Clear data.

2. Try refreshing the page after clearing cache.

3. Make sure your browser and device are fully updated.

4. Check your internet connection to ensure it is stable.

5. If the 404 error persists for all or some books, the issue could be on the server side or specific book pages may be missing or moved.

If the site or specific book pages were recently moved or removed, that would cause a 404 error meaning "Page Not Found." Sometimes content updates cause these errors temporarily.

If you can try accessing WebNovel from another browser or device and see if the books open then, that would also help isolate the problem.

Let me know what you notice, and I can suggest more advanced troubleshooting if needed! Are you able to perform these steps?
