Common issues ​

Facing issues with a source or the app? Here's how to tackle common challenges.

Basic issues ​

Slow loading ​

Sources being slow could stem from site slowness, your internet, or source-imposed rate limits/IP bans.

Reading is laggy ​

  • Caused by oversized images in chapters.
  • Free up RAM.
  • Use sources with smaller images.

App not installed ​

Refer to "Unable to install the app or extensions" section.

Storage access issues ​

"Invalid location" error ​

This error indicates the selected storage location is invalid. Possible reasons include:

  • The app lacks Storage permission.
  • The app cannot access your Mihon storage location folder.

Try these solutions:

  • (For Android 9 and below) In the Mihon app info or your Phone Settings, under the Permissions section, grant Mihon storage permission.
  • Grant Mihon access to your desired storage location again.
    • Navigate to More -> Data and storage, tap on "Storage location", go to your "Mihon" folder and give Mihon access to that folder.
  • Create a new folder or move your existing "Mihon" outside of your device's system folders.
    • Do not use your device's system folders (such as "Documents" or "Downloads"), they are restricted by Android and will cause issues when Mihon tries to access them.
    • Refer to the Storage FAQ for more details.

Storage issues with Android 11+ ​

See the Scoped Storage portion of the FAQ to learn how it affects Mihon in Android 11+ and how to fix it.

Cannot Access SD Card ​

  • Temporarily change the Storage location from your SD card, then change it back to your original storage location and restart the app.
  • Long filepath/filenames could also trigger this issue, as Android's file manager doesn't support >255 characters:
    • If possible, move your "Mihon" to the top-level of your SD card or shorten your "Mihon" folder name.
    • Remember to set the Storage location after moving or changing your "Mihon" folder.

Advanced errors ​

Java.lang Exception: Failed to bypass Cloudflare ​

This error indicates the selected source is protected by Cloudflare.

Consult the Cloudflare guide for solutions. If issues persist, the source might have high Cloudflare protection.

Unable to resolve host / Connection failed / Failed to connect to / timeout / connection reset ​

These errors indicate personal connection issues. Possible causes include:

  • Your ISP or router has blocked the site.
  • The site is down.
  • Weak internet connection.
  • App lacks internet access.

Try these solutions:

  • Switch between networks (WiFi, mobile data) and try connecting with a VPN.
  • Enable DNS over HTTPS under More -> Settings -> Advanced.
    • If this is already enabled, change to a different option, or disable the setting for now.
    • Remember to restart the application after changing this setting.
  • Check the router's protection settings if possible, otherwise, reboot your router.

Caution with changing router settings

If you don't understand how or what to change in your router settings, try the other solutions above instead.

java.security.cert.CertPathValidatorException / Chain validation failed ​

Validation issue with source's certificate.

Try these solutions:

  • Check expired certificate, use SSL checker.
  • Set correct device date and time.
  • In More -> Settings -> Advanced, try Clear cache and Clear cookies.
  • Change network (Wi-Fi, mobile data, VPN).
  • Reboot device.

Attempt to invoke virtual method 'com.hippo.unifile...' ​

Storage-related error causes:

  • Storage full, check device/SD Card.
  • Grant Mihon SD card access in Android settings.
  • Download folder access issues, validate paths.
  • Corrupted or inaccessible writing drive, verify using a file manager.

HTTP errors ​

Encountering HTTP errors? Here's what they mean and how to address them.

HTTP Error: 400, 401 - Bad request / Unauthorized ​

This error suggests that the request could not be processed:

  • (For Trackers) Go to More -> Settings -> Tracking, unlink and relink the tracking service to refresh the authorization.
  • Use WebView to verify if the page or image can be accessed.

HTTP Error: 403 - Forbidden ​

Possible reasons for this error:

  • The selected source has Cloudflare protection. Check the Cloudflare guide for solutions.
  • The source might be down, removed the series, or banned your IP.

    Open WebView to confirm.

HTTP Error: 404 - Not Found ​

This error likely indicates a down source or removed series.

  • Use WebView to verify if the page or image still exists.

    Consider switching to a different source for the series.

HTTP Error: 429 - Too Many Requests ​

This error suggests the source temporarily banned your IP due to fast downloads/reads.

  • Take a break from reading and pause any ongoing downloads. Wait a few hours, then try accessing the content again.

HTTP Error: 5xx ​

Errors like 500, 502, 520, 521, etc., indicate server-side issues on the source's end.

Check the source in WebView to confirm if it's down.

HTTP Error: 1006 ​

This error means a temporary IP ban by the source.

HTTP Error: 1020 ​

This error points to violating a firewall rule set by the site owner. The owner might raise Cloudflare protection or block IPs from outside their country.
