Question details
The user needs to resolve an expiration error that prevents them from downloading digital library books.
- Product
- E-book Reading Application
- Device & OS
- not provided
- Scenario
- Downloading borrowed digital books from a library portal using an authorization file.
- Observed behavior
- The download process halts and displays an E_ADEPT_REQUEST_EXPIRED error message.
Ensure that your internet connection is stable and note the exact time the library loan was initiated, as digital book download links (like ACSM files) are highly time-sensitive.
Correct System Date and Time settings
Syncing your device's date and time prevents expiration mismatches with the library's digital content server.
The E_ADEPT_REQUEST_EXPIRED error primarily occurs when the time on your computer or mobile device does not match the time on the library's server. Because the download authorization is strictly time-bound, even a small discrepancy can cause the request to expire instantly.
Navigate to the system settings on your computer or mobile device and look for the 'Date & Time' menu.
Turn on the option to 'Set time automatically' or sync with an internet time server to ensure absolute precision.
Close your reading application completely, reopen it, and attempt to open the library book file again.
Download a fresh authorization file
If the original download link has genuinely expired, you need to generate a new authorization file from the library.
Enjoy Seamless PDF Reading with WPS Office
Once your library books are downloaded as standard PDFs, use WPS Office to enjoy a lightweight, feature-rich reading experience with built-in annotation tools and multi-device syncing.
- 1. Launch WPS Office: Open the WPS Office application on your computer or mobile device.
- 2. Open the PDF reader: Navigate to the PDF tab and click 'Open PDF' to locate your downloaded library book.
- 3. Customize your reading experience: Use the reading mode, adjust the background color for eye protection, and use annotation tools to highlight important text.
Frequently Asked Questions
What exactly does the E_ADEPT_REQUEST_EXPIRED error mean?
This error means the digital token used to authorize the book download has exceeded its allowed time limit, or your device's clock is out of sync with the server, making the server believe the token is expired.
How long do library download links stay valid?
Typically, authorization files (like ACSM files) are only valid for a few minutes to a few hours after being generated. You should open them in your reading app immediately after downloading.
Does this error mean my library card is expired?
No, it only means the specific download link for that book has timed out. Your library account and loan status are usually unaffected, and you can simply request a new download link.
